Frequently asked questions

Research compounds supplied as a white lyophilized powder for in-vitro laboratory research. Each product page lists its factual identity: name, molecular weight, CAS number, sequence, appearance and storage.

Every product is tied to the batch it came from, and each batch carries its own documentation. You can look up a batch in the COA Library or on the Quality & Testing page to see the certificate of analysis on record for it.

Batch documentation is attached per dispatch. Once a batch is dispatched, its batch and lot number and its certificate of analysis are made available for that order.

A certificate records the product identity, the batch and lot number, the analytical methods used, the date of analysis, and the laboratory that performed the work. Specific figures are recorded on each batch certificate rather than stated as a site-wide claim.

Representative material from each batch is analysed at the University of Southern California, Alfred E. Mann Mass Spectrometry Core, an independent university laboratory, using established analytical methods including LC-MS. The methods confirm identity and characterise the material. Results for each batch appear on its certificate of analysis.

Any specific figures, results, laboratory names or certifications are shown only where they can be evidenced and have been approved for publication. We do not state them as blanket claims.

Store in a cool, dry environment. Refrigerate unopened lyophilized peptides (2–8°C / 36–46°F) to maintain stability. The storage line for each product is shown in its specifications.
