Frequently Asked Questions

What compounds are in the copper-peptide category?

This category covers coordination complexes in which a short peptide binds a copper(II) ion. The catalog item here is GHK-Cu, the tripeptide glycyl-L-histidyl-L-lysine bound to copper, supplied as a lyophilized powder for laboratory research use only.

How is identity confirmed on a copper peptide?

Identity work on a metal-bound peptide has to establish two things: the peptide sequence and the presence of the coordinated metal. Lots are characterized by HPLC for purity and by mass spectrometry for identity, and the batch-specific Certificate of Analysis reports both.

How should copper peptide material be stored?

Lyophilized GHK-Cu ships as a dry powder and is held refrigerated at 2 to 8 C, protected from light. Copper complexes are more sensitive to light and oxidation than unbound peptides, so amber or foil-wrapped containers are the usual choice in a research setting.

Why does copper peptide powder look blue?

The characteristic blue color comes from the copper(II) center rather than from the peptide. A visible color shift or fading in a reconstituted solution is generally read as a signal to re-check the material rather than as normal variation.
