1What is TSA technology?
Tyramide Signal Amplification (TSA™) from PerkinElmer is a technology that improves sensitivity by up to 100-fold whileallowing reduced consumption of primary antibodies or probes.
TSA Biotin Kits use horseradish peroxidase (HRP) to catalyze covalent deposition of biotin labels directly adjacent to theimmobilized enzyme. The labeling reaction is quick (less than 10 minutes) and deposited labels can be detected withstreptavidin conjugates for imaging in brightfield or fluorescence microscopy.
The use of TSA reagents results in a significant increase in sensitivity over standard detection methods, while maintaining
specificity and resolution. Moreover, TSA reagents allow drastically reduced consumption of primary antibody or probe.

Reagents and Materials
Critical Reagents Required but not Supplied Depending upon your assay, additional HRP-labelled reagent to drive the signal amplification reaction may berequired. For example:
o Streptavidin-HRP for use with biotin labeled probes or antibodies (cat. no. NEL750001EA)o Anti-digoxigenin-HRP for use with digoxigenin labeled probes or antibodies (cat. no. NEF832001EA)o Anti-fluorescein-HRP for use with fluorescein labeled probes or antibodies (cat. no. NEF710001EA)o HRP-conjugated anti-species secondary antibody
 Anti-rabbit IgG (goat) HRP (cat. no. NEF812001EA)
 Anti-mouse IgG (goat) HRP (cat. no. NEF822001EA) DMSO (molecular biology or HPLC grade) Streptavidin enzyme or fluorophore conjugate for visualization of biotin labels.

 Blocking Reagent (cat. no. FP1012 or equivalent)

Solutions to prepare
The following buffers and reagents are required for slide preparation and signal amplification
Biotin Tyramide Stock Solution
Biotin Tyramide Reagent is supplied as a solid. Each vial must be reconstituted with DMSO or water as indicated to make
Biotin Tyramide Stock Solution. Biotin Tyramide Stock Solution is stable for at least 3 months when stored at 4ºC. (Note:DMSO freezes at 4ºC; therefore, thaw Stock Solution before each use). Here are recommended dissolution volumes forstock solutions.

TNT Wash Buffer
0.1 M TRIS-HCl, pH 7.5
0.15 M NaCl
0.05% Tween®20
Other wash buffers (such as PBS) may be used. Substitution of 0.3% Triton X-100 for the 0.05% Tween-20 is also possible.
Users should validate the use of alternative wash buffers with their own systems.

TNB Blocking Buffer
0.1 M TRIS-HCl, pH 7.5
0.15 M NaCl
0.5% Blocking Reagent (available separately, catalog number FP1012)
Add Blocking Reagent slowly in small increments to buffer while stirring. Heat gradually to 55°C with continuous stirring tocompletely dissolve the Blocking Reagent. (This should take no longer than 30-60 minutes.) The solution will appear milky.
Bring to room temperature before using. Aliquot and store at -20°C for long term use.
Biotin Tyramide Working Solution
Before each procedure, dilute Biotin Tyramide Stock Solution 1:50 in 1X Amplification Diluent to make Biotin Tyramide
Working Solution. Approximately 100-300 µL of Biotin Tyramide Working Solution is required per slide. Discard any unused
portion of Biotin Tyramide Working Solution.

Recommendations









Do not let slides dry out between steps.
A humidified chamber is recommended for all incubation steps (i.e., a damp paper towel in a covered box).
Before the addition of the next solution, drain off as much of the previous solution as possible to prevent reagent
dilution and uneven staining. After draining the solution, use a Kimwipe™ or similar lint free tissue to blot the areaaround (but not on) the tissue section.
Be sure to use enough volume of each reagent to completely cover sections or cells.
Optional: Use of coverslips may reduce reagent evaporation, especially during steps which require long incubation atelevated temperatures (such as probe hybridization). However care must be taken upon removal to prevent damage
to tissues or cells.
Check for endogenous biotin which may be a source of non-specific background.
If there is too much signal, dilute the primary antibody, probe or HRP conjugate further. TSA kits are designed foruse at 1:50 dilution of the tyramide reagent for optimal results.
First time users should apply TSA to a proven system.

Quenching Endogenous Peroxidase
Activation and covalent binding of TSA reagent is catalyzed by peroxidase. Endogenous peroxidase will be a source of
background, and should be quenched if present. Users should establish the need for doing this and optimal methodology
specific to the tissues or cells being stained. Options include: 0.3% H2O2 to 3% H2O2 in PBS, incubation for 10 to 60 minutes
 0.3% H2O2 to 3% H2O2 in Methanol, incubation for 10 to 60 minutes
For paraffin-embedded tissues, quenching can be done after dewaxing and alcohol rehydration but before the protease
digestion step. For frozen tissue or cell preps, quenching can be done following fixation and before the protease
digestion step. After quenching wash with TNT or 1X PBS buffer for 5 minutes. See Li et al from references section for
more suggestions.

TSA-ISH Optimization
Inadequate optimization of probe and HRP conjugate dilution may be a source of high background and reduced signal.
TSA is ideal for detection of targets that have weak signals using standard detection methods. If the signal is strong withstandard detection methods, dilute the probe until the signal begins to disappear and then proceed with TSA
optimization.
Probe Optimization
 Slide 1: use same probe dilution as standard method.
 Slide 2: 5-fold dilution from slide 1
 Slide 3: 2-fold dilution from slide 2 (further dilution may be necessary) Slide 4: negative control (probe omitted)
HRP Conjugate Dilution
 SA-HRP included with TSA Systems: 1:100 dilution
 Streptavidin-HRP (catalog number NEL750001EA): 1:250-1:1000 dilution
 Anti-fluorescein-HRP (catalog number NEF710001EA): 1:100-1:500 dilution
 Anti-DNP-HRP (catalog number FP1129): 1:100-1:500 dilution
 Anti-digoxigenin-HRP (catalog number NEF832001EA): 1:500-1:5000 dilution
 HRP reagents from other manufacturers: Begin with recommended range for slide applications. Further dilution
may be needed
