How can we help you?

No. All products are sold strictly for laboratory and research purposes. They are not for human or animal consumption, diagnostic, or therapeutic use.

Lyophilized peptides should be stored at -20°C and protected from light. Once reconstituted, store at 2–8°C and use within 30 days for best stability. Avoid repeated freeze-thaw cycles.

Unopened lyophilized vials are stable for 24 months from the date of manufacture when stored properly at -20°C. Each vial is labeled with an exact expiration date.

Use bacteriostatic water or the appropriate solvent for your compound. Slowly inject the solvent down the inner wall of the vial — do not spray directly onto the peptide. Gently swirl until dissolved; never shake vigorously.

Every batch undergoes independent HPLC-MS testing through accredited third-party laboratories (ISO 17025). Certificates of Analysis are publicly downloadable and linked to each batch number.

We test every batch for bacterial endotoxins using the Limulus Amebocyte Lysate (LAL) assay. Our standard is <0.5 EU/mg, ensuring minimal inflammatory response in cell culture work.
