Independent verification

Third-party testing is coming soon.

We're putting independent testing in place for the catalogue. The plan is HPLC for purity, mass spectrometry for identity confirmation, and endotoxin screening where applicable. As lots clear testing, the results will be linked from the relevant product pages.

HPLC
High-Performance Liquid Chromatography. Measures % purity by separating peptide from impurities and degradation products.
MS
Mass spectrometry confirms the molecular weight matches the expected peptide sequence (i.e. you're getting the right molecule).
Endotoxin
LAL test on applicable products to ensure bacterial endotoxin contamination is below threshold.
Tool
Reconstitution & concentration calculator

Once a CoA gives you a molecular weight, this turns vial mass and solvent volume into concentration, molarity and aliquot counts.

Certificates of Analysis, rolling out

We're progressively making downloadable CoAs available across the catalogue. They won't be published for every lot, but where they are, you'll be able to look the lot number up directly on this page. In the meantime, if you need verification on a specific product, get in touch and we'll send what we have on file.
