Procurement documentation

Institutional buyers often file antimicrobial-peptide SKUs beside biosafety and receiving SOPs. Include the lot number, CoA PDF, and packing slip in your audit packet. Verify lots publicly via the CoA Library.

Category FAQ

Are these materials for human use?

No. All listings are research-use-only (RUO) for qualified laboratory and institutional research programs. Not for human or veterinary use.

What CoA documentation is included?

Each released lot includes a certificate of analysis reporting HPLC purity, MS identity, net peptide content, water content, and residual solvents where applicable. Verify lots in the CoA Library.

Can institutions request a quote or NET-30 terms?

Yes. Academic labs, CROs, and qualified institutions can request quotes and NET-30 billing after vendor qualification. See the institutions hub or contact procurement.
