FAQ

Frequently asked questions

Every lot goes through our 6-panel testing protocol: identification by ESI-MS, purification by RP-HPLC, conformity, sterility screening, quantification of net peptide content, and LAL endotoxin screening. We publish the full analytical data in each lot's Certificate of Analysis.

Store lyophilized peptides at -20°C or below for long-term stability. Once reconstituted, store them at 2 to 8°C and use them within a timeframe suited to the compound. Avoid repeated freeze-thaw cycles. Keep them dry and away from direct light.

Orders confirmed by 3:00 PM Pacific on a business day are processed the same day. Orders placed after 3:00 PM Pacific time or on weekends and holidays begin processing the next business day.
