GHK-Cu
GHK-Cu (Copper Peptide)
GHK is a tripeptide (glycyl-L-histidyl-L-lysine) present in human plasma that forms a high-affinity complex with copper(II). Plasma concentration declines markedly with age, which is the observation that originally drove research interest. Gene expression work has reported that GHK-Cu modulates a large number of human genes, and it is among the better-characterized peptides in dermatological and matrix biology literature.
Research applications
- Collagen and glycosaminoglycan synthesis assays
- Gene expression profiling in fibroblast cultures
- Metalloproteinase and antiprotease balance studies
- Copper transport and chelation research
Storage
Store lyophilized powder at -20°C protected from light. Characteristic blue coloration in solution is expected and indicates intact copper complexation.
Reconstitution
Reconstitute with bacteriostatic water. Solution will appear deep blue — this is the copper(II) complex, not contamination.
