Lab results
Every lot we release is analysed by a third-party laboratory before a single vial ships. Search by compound, lot number or lab, and open the certificate that matches the batch printed on your vial.

What a certificate
actually proves.
HPLC purity
Reverse-phase chromatography separates the target chain from truncated and deleted sequences. The percentage is the area of the main peak against everything else on the trace.
Mass-spec identity
Electrospray ionisation confirms the observed molecular mass matches the theoretical mass of the declared sequence. Purity without identity proves nothing.
Endotoxin (LAL)
A limulus amebocyte lysate assay measures bacterial endotoxin load, reported in EU per milligram. Relevant for any cell-based work.
Water content
Karl Fischer titration on the lyophilised cake. Residual moisture drives both mass accuracy and long-term stability.
Lot traceability
The lot on the certificate is the lot printed on your vial. If the two do not match, do not use the material — contact us instead.
Independence
Analysis is commissioned from laboratories that do not synthesise our material and are named on the certificate.
