Solubility Tes�ng Service
Solubility Testing Service makes working with hydrophobic peptides easier by taking
the guesswork out of peptide solubility. Solubility testing deliverables include a reportcontaining the gross peptide concentration of your peptide in multiple solvents at
various pH, which will save your time, money and peptide stock.You can request thesolubility test with any solvent you want.

TFA Removal Service Free Upgrade
Most custom peptides are delivered as lyophilized trifluoroacetic acid (TFA) salts,
and can contain as much as 10-45% TFA. Residual TFA in custom peptides has
been shown to interfere with cellular assays , which inhibits cellular proliferation insome instances and increases cell viability in others. GenScript’s TFA Removal
Service can guarantee the removal of TFA to as little as <1%.

* If Report is selected for Standard TFA removal service, extra cost and 1 day will be needed.

Endotoxin Control & AnalysisNEW
Endotoxin in pepitdes can decrease cell viability or cause an immune
response. To improve your experimental success rate, our updated endotoxin
control service guarantees endotoxin levels in custom peptide preperation tobe ≤0.01 EU/µg.
