GHK-Cu Copper Peptide: Research Applications and Handling

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). Unlike the larger receptor-agonist peptides, GHK-Cu is a small copper-binding peptide studied in dermatology, wound-healing, and biomaterials research models.

Identity and composition

• Compound: GHK-Cu (copper tripeptide)
• Peptide sequence: Gly-His-Lys, complexed with copper(II)
• CAS: 49557-75-7
• Molecular weight: approximately 404 Da (copper complex)
• Format: lyophilized powder in a sealed research vial

Because GHK-Cu carries a coordinated copper ion, its characterization and handling differ from non-metallated peptides. A batch Certificate of Analysis documents identity and reported purity for the specific lot.

Research context

GHK and GHK-Cu are studied for their copper-binding chemistry and their behavior in extracellular-matrix and tissue-research models. Georgia institutions with biomaterials and tissue-engineering programs — for example the research community around Atlanta — represent the kind of qualified laboratory settings in which such reference materials are used. TagPep supplies the material; the research conclusions belong to the underlying studies.

Handling

Copper peptides should be protected from inappropriate light, heat, and moisture, consistent with general lyophilized-peptide storage. Confirm the lot on the vial against the analytical documentation before use.
