Product information
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), in which the peptide coordinates a single copper(II) ion in a 1:1 stoichiometry to form a characteristic deep cobalt-blue complex. First isolated from human plasma by Pickart in 1973, GHK is a small signal-peptide sequence; the copper-bound form is the compound most often referred to in the literature as “copper peptide” or “copper tripeptide-1.” This product is supplied as a lyophilized powder in multiple sizes, synthesized and complexed to research grade, and characterized by HPLC (purity) and LC-MS (identity), with a lot-specific third-party Certificate of Analysis available before purchase. It is intended exclusively for in-vitro laboratory research and analytical applications. In the research literature, GHK-Cu is referenced as a reference copper-peptide complex used as a tool compound in the study of copper coordination chemistry, peptide–metal binding, and gene-expression research in cell-based models.
