OP-GHK Cu / 10 Vial

Product Description

Compound Identity

OP-GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper(II) Complex) is a tripeptide-metal coordination complex (3 amino acids; free peptide MW ≈ 340.4 Da; copper(II) complex MW ≈ 402.9 Da) first isolated through biochemical research conducted by Loren Pickart in the 1970s. The molecule consists of the tripeptide Gly-His-Lys coordinated to a copper(II) ion. It is intended strictly for laboratory and research purposes.

Receptor Selectivity & Binding Profile

OP-GHK-Cu does not act through a single defined receptor pathway. Its biological activity in research models is mediated through copper(II) coordination chemistry. The Gly-His-Lys sequence forms a square-planar copper(II) coordination complex with high binding affinity (Kd ~10^-15 M at physiological pH), characterized extensively in coordination chemistry literature.
