Importance of Stable Isotope Standards and Their Implementationin Mass Spectrometry

Technical

The implementation of mass spectrometry (MS) in the preclinical/
clinical laboratory has been garnering more attention over the
past couple of decades.1 Among the reasons for this are theperformance benefits that MS-based methods can afford.
This pertains to the high specificity, reproducibility, and sensitivity
achieved through tandem MS operations (e.g., selected or multiple
reaction monitoring). As with any technology, there are a few
limitations worth noting. These include the upfront instrument
investment and its complexity, as well as the result turnaround time.
Nonetheless, as the breadth of instruments and data analysis tools
continue to advance, the limitations appear to be diminishing,while the overall merits, relative to historical clinical techniques,
are amplifying. Example applications that have capitalized on theanalytical power of mass spectrometry include endocrinology,2therapeutic drug monitoring,3 and newborn screening (for inborn
errors of metabolism).4 The aim of these, and other clinical MS
screens, is to help improve the path to diagnosis. From this,specific treatments can be effectively implemented at the earliest
time leading to enhanced patient care and longevity.
To facilitate accurate MS-based measurements, stable isotopelabeled standards must be incorporated. The preferred approachhere is to add the labeled standard in a precise and constantamount to both the experimental samples, as an internal standard(IS), as well as the standard curve and QC samples. For utmost
accuracy, the curve samples should be generated in an equivalentsample type such that the matrix effects and extraction efficiency
are identical. Only by adding the labeled standard as an IS canrecovery differences be effectively resolved. With IS use, the typeand its point of insertion are two critical factors that a researcher
faces in designing a clinically relevant, MS-based method.
This is critical to qualitatively evaluate the assay’s effectivenessand to help guide corrective measures, as necessary.
The nature of IS can take many forms but is conventionally acompound, or mixture of compounds, that has been labeled with
one or more stable isotopes (e.g., 13C, 15N, and/or D). The positionand number of stable isotopes in a given compound is predicatedon the sample preparation and method of analysis. If, for instance,
D-labeling is preferred for a certain metabolite, the labels must be
inserted at nonexchangeable positions to mitigate the effects ofhydrogen-deuterium exchange. Regardless of the type of isotope
incorporated, the labeled standards should ideally bear a total mass
shift of 3 Da minimum from its unlabeled counterpart (to enableswift metabolite MS analysis) and be well characterized (e.g., forchemical and/or chiral purity, isotopic enrichment). In terms of thenumber of labeled standards required for a given experiment, it isrecommended that this number equate to the number of target
analytes. While this is generally practical for small panel analyses(as would be typical in a clinical experiment), it is common withlarge panels (as utilized in preclinical experiments) to select certain
labeled standards as surrogates for compounds that lack a labeledanalogue. This practice is considered acceptable in quantification
exercises provided that the surrogates exhibit similar elution times,
and thus bear similar physicochemical properties as their native
targets.
Given the complexity of human biological samples, in termsof depth and breadth of analytes, it is recommended that thelabeled IS be added as early as possible in the analytical workflow.
In so doing, losses or modifications that occur during the sample
preparation and processing steps can be adequately accountedfor. Since the standard is designed to match its native analogue
and behave similarly (in terms of its separation, ionization, andfragmentation), any changes that occur on one will, in theory, be
reflective on the other. Therefore, in analysis, the analyte can be

quantified using relative ratios (i.e., unlabeled/labeled) of peakareas as opposed to their absolute values. In addition to theexperimental samples, this approach is applied to other sample
types, such as standard curve and curve QCs (at low, medium,and high concentrations). While the response of the labeled andunlabeled analyte will differ in curve and QC samples, the point of
elution will not (valid particularly with 13C and/or 15N standards),
enabling their relative ratios for quantitation or performanceassessment to be effectively determined.
The importance of stable isotope-labeled standards in the rapidly
evolving clinical MS field is becoming increasingly more recognized.
This pertains to both small and large molecule analysis,5 with

applications covering diagnostic testing and drug therapy
monitoring, among others. Regardless of the application type,a well-executed clinical MS method should be automated andwell controlled. In the assays deemed fit for purpose, the highly
characterized standards should be inserted for not only accuratequantitation, but also for system suitability reliance to enable
complete accounting of all possible losses or errors.6 This relates
to human errors (e.g., improper pipetting), chemical errors(e.g., analyte extraction, hydrolysis), and instrument errors(e.g., ion suppression, matrix effects). The labeled standards
that CIL provides can be, and have been, utilized in this realm.
The product listing, perspectives, and applications herein provide
such examples.

Benefits of 13C vs. D Standards in Clinical Mass Spectrometry
Measurements

The capabilities of mass spectrometry (MS) have made this analyticaltechnique an invaluable tool in clinical-based developments andapplications. As with any clinical test, accurate and precise results
are paramount toward correct diagnosis and treatments. In MS
testing, reliable results are best achieved by the inclusion of stable
isotope-labeled standards. The utility of such standards has been
demonstrated in clinical and translational research (see page 6of this catalog for a background article), with their benefits
including the ability to help compensate for matrix effects and ion
suppression.1 For optimum results, the standards should be added
as early in the analytical workflow as possible, such that they caneffectively normalize the variations that may arise throughout theexperimental stages. The nature of labeled standards is a criticalelement of a method and is predicated on its availability/cost, as
well as the study design and research aims. Important to recognizein the standard selection process is the isotope differences (e.g.,
between 13C and D) and the potential impact this may have in the
pre-analytical (e.g., storage and handling) and analytical (e.g.,sample preparation and processing) phases. As standard selection
is not always a straightforward procedure, this article compares
the commonly used 13C and D isotopes from production to analysis
in an effort to edify the challenges and guide future selections.
Standards labeled with 13C (and /or 15N) have demonstrated broadresearch utility over the past couple of decades. This stems partly
from the chemical stability of its isotope. Its stability ensuresthat the isotope remains intact irrespective of the experimental
methodology employed (e.g., multidimensional LC or derivatizationbased GC prior to MS/MS). In other words, the 13C (and 15N) isotope
remains positioned at its point of synthesis throughout all stagesof an analytical workflow (includes extraction, derivatization,
separation, and analysis in metabolomics). This provides flexibility
to the end user as there is no limitation on the choice of sample/
solution preparation nor the mode of MS/MS analysis. Since
13
C (and/or 15N) standards have exceptional isotope stability, as
compared to their deuterated counterparts, these can be inserted
at an early stage of sample preparation. Of additional benefit isthat this type of labeled compound co-elutes with its corresponding
unlabeled (i.e., native or endogenous) analyte during chromato­graphic separation. This co-eluting result is optimal in correcting
for both ion suppression and matrix effects. Further to the benefits,
13
C (and/or 15N) standards are absent from isotope scramblingor loss during ionization and collisional activation in the mass

spectrometer. Owing to these collective merits, 13C (and/or 15N)
standards have incurred great value in preclinical and clinical MS
applications (from qualification to absolute quantification).
Despite the benefits of 13C (and 15N) labeling, the production ofsuch standards could entail complex and laborious synthesis. Whilecarefully selected structural analogues (with 13C and/or 15N) may
instead be used in cases where it is cost or time prohibitive toobtain or synthesize the required standard, deuterated standards
are an alternate option to consider. These are comparatively
straightforward to prepare, but invoke a number of potential issues
at the pre-analytical and analytical phases. The first pertains to theisotope stability. If the D-label is placed at an exchangeable position(i.e., at acidic and polar groups), it could be susceptible to an
isotope effect during storage and later in analysis. In this effect,
the location of deuterium may scramble or undergo an exchange
reaction with protium in solution or in the gas phase. Anothersituation to consider is deuterium loss on specific compounds fromenzymatic reactions (e.g., deuterium abstraction from fatty acids
due to fatty acid desaturation).2 The impact of these collective
effects could be significant and is best illustrated by a hypotheticalexample. In a complete exchange scenario, for instance, the labeledsignal at the mass spectrometer would be unmeasurable, while theunlabeled signal (i.e., M+0) would be elevated. This would provide
an invalid view of a patient’s biochemistry and a false impressionof the assay’s fitness, a result that would clearly contribute to“imprecision medicine” in laboratory diagnostics. While thisdeleterious impact could be overcome by selecting alternate MRM
transitions (i.e., at sites verified to have label due to consistentscrambling), a preferred approach would be to incorporate
deuterium at chemically inert, nonexchangeable positions. Doingso would aid its stability, but the integrity of the deuterated
standards would still need to be validated at all phases of theanalytical workflow (from reconstitution through extraction to
MS analysis). Complicating these assessments is the difference inphysicochemical properties between deuterium and hydrogen.
The difference causes deuterated standards to typically exhibit analtered chromatographic retention from its native analogues.3
This elution impact is most pronounced in LC separations, but
may also occur in GC separations. The shift could complicate theaccuracy/reproducibility of identification and quantification incomplex biosample analysis, such as human plasma or urine.
Only if the stability and effectiveness of deuterated standards areisotope.com

first demonstrated can its subsequent use in large-scale analysis
be considered acceptable for critical decision-making studies(e.g., newborn screening, therapeutic drug monitoring, vitamin D
deficiency).
To summarize, there are an array of factors to consider indesigning experiments and implementing methods. Importantamongst them is the type of labeled standard. As describedabove, 13C (and 15N) standards provide excellent isotope stability
and analytical reliability. This means that the position of label is not
impacted by the pre-analytical and analytical processes. Since thistype of standard has equivalent physicochemical properties as its
unlabeled counterpart, we consider these to be ideal toward theaccurate and reproducible quantitation of small or large molecules.
Deuterated standards, in contrast, may exhibit isotope instability| Stable Isotope Standards for Mass Spectrometry

and an exchange or scrambling effect during storage and theexperimental phases. These effects are magnified if the D-label isincorporated at exchangeable positions. Even if deuterium is placedat nonexchangeable positions, development time must be allottedfor stability testing (e.g., at storage, in autosampler) and method
evaluation (e.g., for mobile phase impact, preferable MRM
transitions).4 That said, if validations have been performed andother options (e.g., 13C standards or surrogates) are absent, thenthis route could be suitable long-term. Overall, although Cambridge
Isotope Laboratories (CIL) offer a multitude of variably labeledstandards (encompasses vitamins, steroids, and fatty acids/lipids,
amongst others), our recommendation is toward a 13C (and/or 15N)
variant, when possible, for accurate/reproducible quantification inclinical MS-based analyses.

Free Amino Acids and Their Derivatives
Amino acids play critical roles in biological functions as building blocks of peptides and proteins, as well as intermediates of various
metabolic pathways (e.g., citric acid cycle, urea cycle). These compounds are also reported to influence the pathogenesis and propagationof metabolic disorders /disease, with clinically designed biomarker research aimed to detect disease at the earliest stage.
To aid qualitative and quantitative research, CIL offers an array of unlabeled and stable isotope-labeled free amino acids. These can beused as internal standards or NMR probes in MS- and NMR-based research studies. The amino acids are canonical (e.g., arginine, lysine,
phenylalanine) and non-canonical (e.g., beta-alanine, citrulline, ornithine). These are available in their uniform or specifically labeled(with 13C, 15N, D, and /or 18O) forms, in research or MPT grade.

| Stable Isotope Standards for Mass SpectrometryProtected Amino Acids
Stable isotope-labeled peptides have demonstrated to be an effective means to quantify endogenous proteins in basic and translationalbottom-up proteomics. In these experiments, the labeled peptides are employed as internal standards, where they serve as molecularsurrogates of the target proteins enabling relative or absolute protein quantitation.
From a development standpoint, the peptides are produced in a step-wise manner by solid phase peptide synthesis using amino acidbuilding blocks with N-terminal, 9-fluorenylmethoxycarbonyl (Fmoc) or tert-butoxycarbonyl (t-Boc) protecting groups. To help facilitate
the synthesis of isotopically labeled peptides, CIL offers an assortment of uniformly or partially labeled Fmoc and t-Boc amino acids.

Bile Acids
The analysis of bile acids (BAs) in biofluids is a developing and growing MS ‘omics field. These steroid-like compounds act as detergent
that assist in the breakdown of fats. The primary BAs are synthesized from cholesterol in the liver, while secondary BAs are converted fromprimary BAs in the colon. The bile acids can also be conjugated with glycine or taurine in the liver, which increase their solubility in water.
Bile acids have gained clinical attention by their linkage to colon cancer, liver disease, chronic diarrhea, cholestasis, hyperlipidemia, andgallstones. CIL is pleased to offer an extensive panel of primary and secondary BAs, in their free acid and conjugated salt forms. These
research-grade products are available as isotopically labeled and/or unlabeled standards in solution (at 100 µg /mL in methanol) and/or neatform.

Caffeine and Its Metabolites
Caffeine is a psychoactive stimulant of the central nervous system that is extensively consumed worldwide. MS-based research into thekinetics/metabolism of this compound and its metabolites (e.g., paraxanthine, theobromine, theophylline) has revealed insight into
its health impact and abuse in humans. Studies further suggest an influence on pharmacological activity and neurodegeneration(e.g., Parkinson’s disease); thus, strengthening a need for its robust clinical analyses.
CIL offers stable isotope-labeled caffeine and a collection of isotopically labeled metabolites for basic and translational quantitative research.
These standards are available in various labeling patterns, with alternate compounds or labels evaluated upon request.

Carbohydrates
Carbohydrates are integral biomolecules to the function and process of living systems (e.g., in cell-to-cell signaling, immune responses,
protein folding). Although this family of compounds is structurally diverse and complex, analysis by LC- and GC-MS techniques has been
well adopted in the metabolomics field. Clinically, the quantitative analysis of sugars in human biosamples is of increasing importance forsuch disease screenings as cardiovascular and nonalcoholic fatty liver disease (NAFLD).
In addition to the classic monosaccharides (e.g., glucose, fructose, ribose) and sugar alcohols (e.g., erythritol, sorbitol, xylitol), CIL offers
a number of other stable isotope-labeled carbohydrates. The list includes monosaccharides, under the pentose (e.g., arabinose, erythrose)and hexose (e.g., galactose, mannose) classes, disaccharides (e.g., lactose, maltose, sucrose), and polysaccharides (e.g., starch). These
compounds are supplied with various labeling patterns as neat standards, in research or MPT grade.

Carnitine and Acylcarnitines
Carnitine and acylcarnitines play an essential role in fatty acid metabolism. Metabolism disorders of fatty acid oxidation and several organic
acidurias impose major clinical manifestations (e.g., hypoketotic hypoglycemia, skeletal myopathy, liver disease, and /or failure). These arelargely attributed to enzymatic deficiencies and can be monitored through carnitine/acylcarnitine measurement.
To help facilitate metabolic screening exercises, CIL is pleased to offer a variety of stable isotope-labeled and unlabeled carnitine/acylcarnitine
standards. Please refer to page 60 for a list of mix offerings; individual standards are noted below.

Drugs and Their Metabolites
The field and scope of drug screening/analysis continues to expand worldwide. Example areas of focus include therapeutic drug monitoring,drugs of abuse, prescription monitoring, and clinical toxicology. The nature of those monitored or identified in the MS-based analysis include
psychoactive drugs (e.g., benzodiazepines, cannabinoids, hallucinogens), pain-management drugs (e.g., analgesics, opiates, skeletal muscle
relaxants), disorder-related treatment drugs (e.g., anticonvulsants /antiepileptics, antipsychotics, erectile dysfunction), and infectious diseaseor disease-related treatment drugs (e.g., antibiotics, antiarrhythmics).
CIL is pleased to offer a broad collection of unlabeled and stable isotope-labeled standards to aid the qualitative/quantitative analysis ofdrugs and their metabolites. These encompass a multitude of classes (e.g., analgesics, benzodiazepines, cannabinoids and its agonists,
opiate and opioid analgesics, stimulants). The offerings are individual standards and /or class-specific mixtures in predominantly theirconcentrated solution form.
Available from CIL for customers in the US, Australia, Canada, and Switzerland. Contact us for sourcing details for other destinations. Products listed with anasterisk are available globally.

Fatty Acids and Lipids
Fatty acids and lipids are important biological compounds that are essential to the regulation and control of cellular functions andmetabolic pathways. These biomolecules are also tied to the energetic balance of an organism. Their qualitative /quantitative analysis
has emerged to better understand the underlying pathophysiology, as well as to identify new biomarkers or diagnose existing ones.
To aid such research initiatives, CIL is pleased to offer a multitude of stable isotope-labeled and unlabeled fatty acids and lipids.
The fatty acids cover saturated and unsaturated classes, while the lipids include ceramides (e.g., N-palmitoyl-D-sphingosine,N-oleoyl-D-sphingosine), and phospholipids (e.g., dodecylphosphocholine, dipalmitoyl phosphatidylcholine), as well as triacylglycerides(e.g., tripalmitin, tristearin, triolein). These are available in various labeling patterns (i.e., uniform, partial), forms (i.e., free acid, salt,
ester), and material grades (i.e., research, MPT).

Gases
Calibration Standards
We are pleased to offer four CO2 standards for use in 13C-urea breath analysis. These gas calibration standards are designed to mimic
13
CO2 levels in normal breath (baseline calibrant) and at three enriched levels (low-, mid-, and high-level calibrants). Each is gravimetrically
prepared and analyzed for 13C content by isotope ratio mass spectrometry (IRMS). The 13C content for the baseline standard is expressed asdelta value vs. PDB (Pee Dee Belemnite), with the enriched calibrant gases additionally reported as delta value above baseline (see lot-specific
CoA for details). Please visit isotope.com for a complete listing of high-purity gases and mixtures.

Metabolomics Mixtures and Kits
Metabolomics is an increasingly important and growing area of research. The use of stable isotopes (as internal standards), in combination
with analytical techniques such as mass spectrometry, allow researchers to identify and quantify metabolites in a given biological sample.
This information can be used to better understand disease mechanisms, evaluate drug responses, and assess putative biomarkers,
amongst other targeted applications. To help facilitate such initiatives, CIL is pleased to offer a variety of mixes and kits. These aredesigned to aid ease of use in untargeted and targeted metabolomics exercises (e.g., in quantification, qualification, quality control,
system suitability). The mixtures are offered neat or as solutions, while the kits are additionally supplied with a user manual. The manuals
outline general procedures and processing tables (i.e., platform parameters and conditions), as well as alternate method suggestions anddata analysis guides for user reference. Supplemental figures and references in the user manuals provide additional user support.

Mouse Feeds
The study of animal models, using a metabolic labeling technique called SILAM (stable isotope labeling of mammals), can provide useful
insight into human disease. To help facilitate this branch of research, CIL offers labeled/unlabeled Mouse Express® mouse feeds in their irradiated and nonirradiated form. Consumption of an isotope-enriched chow enables metabolically labeling of an entire mouse proteome with
an isotopically labeled compound. Traditionally, the feeds incorporate isotopically labeled canonical (e.g., lysine, leucine, valine) and/or noncanonical (e.g., azidohomoalanine) amino acids, with labeling on individual or multiple isotopes (e.g., NeuCode™ lysine). Diets that comprise15
N and unlabeled feed prepared with spirulina are also available. For expanded research opportunities, the labeled feed can be packaged
together in a kit with the unlabeled in standard units of 1 kg. Please see the SILAM application page for product details and isotope.com
for product inquiries.

MS/MS Screening Mixtures and Standards
The utility of stable isotope-labeled standards for MS/MS screening is gaining traction worldwide. To support such research endeavors
and enhance method adoption, CIL is pleased to offer a breadth of high-quality, stable isotope-labeled mixtures. These mixes containa collection of stable isotope-labeled standards (e.g., 12 amino acids in NSK-A) and are class-specific (e.g., amino acids, carnitine/
acylcarnitines, steroids). These are available in 10-vial sets or single vials and are suitable for metabolite quantification in isotope
dilution MS (IDMS) experiments. Also listed here are example individual standards used in MS/MS screening research. Please referto page 124 for CE-mark amino acid and acylcarnitine mixes.

Neurotransmitters and Their Metabolites
Neurotransmitters are small chemicals in the central nervous system that modulate and regulate brain function. Signals are relayed fromneuron to neuron by release, upon stimulation, from a synaptic vesicle into a space where it can bind to a receptor. These molecules
can be grouped into several classes, such as catecholamines (e.g., dopamine, epinephrine) and indolamines (e.g., melatonin, serotonin).
MS analysis of neurotransmitters in human biosamples, such as urine, is a clinically relevant area as they mediate homeostatic function,
modulate neural activity, and have been correlated to the pathogenesis of neurodegenerative diseases (e.g., Alzheimer’s).
CIL offers an array of stable isotope-labeled neurotransmitters. These research-grade materials are available in their solution and/or neatform.

Nucleic Acids
Nucleic acids are necessary biomolecules of living systems, being fundamentally important to a multitude of cellular processes. Its basic
building blocks are nucleobases (e.g., adenine, cytosine, xanthine), nucleosides (e.g., adenosine, guanosine, inosine), and nucleotides(e.g., ATP, CMP, dGTP). The qualification /quantification of these compounds, and their synthetic analogues (e.g., 5-fluorouracil), in
biosamples is performed preclinically and clinically to address a number of purposes. This includes the screening of metabolic errors
and the efficacy evaluation of drug treatments (be it anticancer, antiviral, or immunosuppressive), among other target areas.
CIL offers an array of stable isotope-labeled nucleic acid building blocks for MS- or NMR-based research. These standards are available
in a variety of labeling patterns and quantities.

Organic Acids and Their Conjugate Salts
Organic acids (OAs) play essential roles in energy metabolism pathways (e.g., glycolysis, tricarboxylic acid cycle), with the short-chained
OAs emerging as important regulators of host immune response and transcriptional regulation.
To aid quantitative research in preclinical and clinical studies, CIL is pleased to offer a collection of stable isotope-labeled and unlabeled
OAs and their conjugate salts. These encompass monocarboxylic (e.g., acetic, lactic), dicarboxylic (e.g., malic, succinic), and tricarboxylic(e.g., cis-aconitic, citric) acids.

PeptiQuant™ Plus Assay Kits
Researchers in academia and life science industries continue to adopt a targeted, bottom-up MS-based workflow for protein biomarker
evaluation. Biomarker verification / validation requires absolute quantification of surrogate peptides in the sample matrix, a requirementthat is best achieved using well-characterized standards. To ensure robust quantitative measurement, quality control (QC) checks should beroutinely performed. CIL offers a collection of PeptiQuant™ Assay Kits (from MRM Proteomics Inc.) for QC and biomarker assessment using
bottom-up LC-MS /MS methodologies. The QC kits are designed to evaluate the performance of an LC-MS platform, either alone or in
combination with a human or mouse plasma proteomic workflow. The biomarker assessment kits (BAKs) are intended to help researchers
screen target panels of candidate protein disease biomarkers in human or mouse plasma samples. Platform-specific kits are listed below.

Pharmaceutical and Personal Care Products
Concerns about environmental and human exposure to pharmaceutical and personal care products (PPCPs) has grown significantly over
the years. The classification of PPCPs encompasses a broad range of chemicals, ranging from antibiotics to hormones to food and drinking
water impurities. Isotope-labeled standards are necessary in the qualitative/quantitative analysis of PPCPs, especially in complex matrices
such as sewage sludge and biosamples, as well as in applications where ion suppression or enhancement are of high concern. CIL, withguidance from leading laboratories around the world, works diligently to produce high-quality, native and stable isotope-labeled standards
for analysis of PPCPs. Please see isotope.com for the listing and details of our PPCP standards.

Protein Expression Reagents and Kits
The use of stable isotope-labeled proteins in MS- or NMR-based proteomics are useful standards as they exhibit similar physicochemical
behavior as their endogenous (or natural) counterparts. Adding a labeled protein, either as an individual standard or as a mixture, at the
beginning of a workflow can therefore help normalize for any variation that may occur throughout an analytical run. When used as
quantitative standards, as is the case in preclinical and clinical MS applications, validated biomarkers can be screened for diagnostic or
prognostic purposes.
To help facilitate the production of isotope-enriched recombinant proteins, CIL offers a diverse array of isotopically labeled prokaryotic andeukaryotic cell growth media. CIL also offers various wheat germ cell-free kits, such as the Premium Plus Expression Kit for MS, for protein
expression. The listing below outlines our current offerings. The researcher perspective that follows discusses the different approaches toquantifying proteins using stable isotope-labeled proteins or peptides as internal standards.

Steroids and Hormones
Steroids and hormones play vital roles in the regulation of a diverse array of cellular functions and physiological processes. These pertain
to development, reproduction, homeostasis, and metabolism, among others. Accurate quantification of this compound class is essential
for basic and clinical translation research. This can be achieved by spiking an isotopically labeled steroid standard(s) into a sample ofinterest, such as plasma or urine, with measurement performed by an MS- or NMR-based approach.
CIL offers a variety of stable isotope-labeled and unlabeled steroids and hormones. These are available in different labeling patterns
in their neat and/or solution forms.

Vitamins and Their Metabolites
Vitamins are organic compounds that directly or indirectly participate in organisms’ biochemical reactions. These are divided into twoclasses, based on their solubility in fat (includes A, D, E, and K) and water (includes B and C).
CIL offers unlabeled and stable isotope-labeled vitamins as neat compounds and/or in solution at specified concentrations. These canbe used in a wide range of applications, such as metabolism and pathophysiology explorations, as well as disease biomarker evaluationin preclinical and clinical MS studies (e.g., vitamin D deficiency). These standards help facilitate accurate and precise quantificationof endogenous metabolites in biological matrices.

Urea
To complement the growing area of urea-based research in the preclinical and clinical fields (e.g., as biomarker of respiratory andrenal diseases), CIL offers a variety of stable isotope-labeled urea compounds. These are available in various labeling patterns andin different material grades (i.e., research, MPT, cGMP). In one example application, a 13C urea breath test can be used to accurately
and noninvasively diagnose H. pylori infections, such as peptic ulcer disease and gastric cancer. This test involves the oral ingestionof cGMP-grade 13C urea, with measurement of the 13CO2 to 12CO2 area ratios in the expired breath facilitating diagnosis.

Research Use of Products
CIL manufactures highly pure research biochemicals that are
produced for research applications. As a service to our customers,some of these materials have been tested for the presence ofS. aureus, P. aeruginosa, E. coli, Salmonella sp., aerobic bacteria,
yeast, and mold, as well as the presence of endotoxin in thebulk material by taking a random sample of the bulk product.
Subsequent aliquots are not retested. Presence of endotoxin is
assessed by determining endotoxin content following establishedprotocols and standardized limulus amebocyte lysate (LAL) reagents.
Any materials listed in our catalog or website that are designated as“MPT” in the item product number (e.g., DLM-349-MPT) containthese tests as part of release specifications.
If a product does not have an “MPT” designation, CIL may be able
to provide microbiological testing on the product. Depending on
the compound and the quantity ordered, an additional fee may
apply for the testing. Please note that microbiological-tested
products are not guaranteed to be sterile and pyrogen-free when
received by the customer, and microbiological testing does not
imply suitability for any desired use. If the product must be sterileand pyrogen-free for a desired application, CIL recommends thatthe product be packaged or formulated into its ultimate dose formby the customer or appropriate local facility. The product should
always be tested by a qualified pharmacy/ facility prior to actual use.
CIL research products are labeled “For research use only. Not
for use in diagnostic procedures.” Persons intending to use CIL
products in applications involving humans are responsible forcomplying with all applicable laws and regulations, including, but
not limited to the US FDA, other local regulatory authorities, andinstitutional review boards concerning their specific application
or desired use.

It may be necessary to obtain approval for using these research
products in humans from the US FDA or the comparable
governmental agency in the country of use. CIL will provide
supporting information, such as lot-specific analytical data and test
method protocols, to assist medical research groups in obtaining
approval for the desired use. An Enhanced Data Package (EDP) isalso available (see next page for an overview of the technicalpackage contents).
CIL will allocate a specific lot of a product to customers who arestarting long-term projects requiring large amounts of material.
Benefits from this type of arrangement include experimental
consistency arising from use of only one lot, no delay in shipments,
and guaranteed stock. Please note that some CIL products havea specific shelf life and cannot be held indefinitely. If interested,
please contact your sales manager for further details.
Because of increasing regulatory requirements, CIL manufacturesdifferent grades of materials to help researchers with thoserequirements. Listed below are the grades of materials that
CIL currently manufactures:

Newborn Screening Standards
CE Mark in vitro Diagnostics (IVD)
Newborn screening (NBS) is an analytical or physical screening process used to test neonates for inherited or congenital disorders related
to inborn errors of metabolism (IEM). IEMs are caused by the deficiency, absence, or alteration of specific enzymatic reactions. The goalof NBS is to detect metabolic errors at the earliest stage of development, such that treatment can be initiated and irreversible damage
to the central nervous system can ultimately be avoided.
To help facilitate IEM screens (e.g., for phenylketonuria, maple syrup urine disease, medium-chain and very-long-chain acyl-CoA
dehydrogenase deficiencies), CIL is pleased to offer two types of CE-marked in vitro diagnostic (IVD) medical devices: amino acid reference
standards (NSK-A-CE) and carnitine/acylcarnitine reference standards (NSK-B-CE). When used as directed, these devices provide solutions ofstable isotope-labeled standards at defined concentrations. The ready-to-use assays can be implemented to measure the concentrations oftarget analytes (amino acids in NSK-A-CE; free carnitine/acylcarnitines in NSK-B-CE) in a range of biosamples (e.g., dried blood spot, urine)by a variety of analytical techniques (e.g., FIA-MS/MS, LC-MS/MS).

bodily fluids.
Each vial (packaged 10 vials per box) contains only a dry mixture of 12 isotopicallylabeled amino acids. Complete reconstitution in 1 mL of solvent will produce theconcentrations presented in the concentrations table.

Instructions for Use/Method of Reconstitution
To reconstitute the NSK-A-CE Amino Acid Reference Standards solution,
the following procedure is suggested: add 1 mL of purified water (or 1:1
purified water:methanol) to the dry mixture in the vial. Vortex the vial manuallyfor 1 minute, then auto-vortex for 30 minutes or until solids are dissolved. Storethe reconstituted standards in a tightly sealed vial refrigerated at 2-8°C and awayfrom light. To maintain the integrity of the solution, store the sealed vial in asecond sealed container. Discard the solution after 1 month.
