Where do the identity data come from?

From our product table, shown on each product page with its source; where the table gives a formula but no mass, the mass is calculated from the formula and marked as such. Literature is cited with its PubMed number or DOI.

Why do CAS numbers differ between suppliers?

Usually because they belong to different forms — salt, copper complex, free peptide, a two-peptide material — or to a superseded registry entry. Each page says which form its values refer to.

Is there an independent analysis?

Yes: HPLC and MS reports by a third-party analytical laboratory in Tianjin, China, and reports that customers commissioned from an independent laboratory. First-page previews are on the Batch COA page and the product pages; the complete report is available from sales.

What paperwork comes with an order?

A written quotation with the unit price per kit, shipping cost and lead time, and the batch COA of the lot supplied. Other tests are agreed in writing before the order.

Research laboratories

Research peptides for research laboratories.

Each product page gives the sequence, formula, molecular weight and CAS with the source of every value. Every lot of a stocked peptide has a batch COA with HPLC purity, MS identity, endotoxin and fill.
