Lab results
Certificates of analysis are published here as lots are released, and only once the signed document has been received from the testing laboratory. Nothing on this page is generated: if a lot has no published certificate, its product shows “COA pending” instead of a purity figure.
Check your lot
Type the lot number printed on your vial label to open that lot's certificate. A lot without a published certificate shows "COA pending".

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. A laboratory is named on this site only when its name appears on the uploaded certificate for that lot.
