Characterization

What it is, stated plainly.

What it is

The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). The copper ion is coordinated by the imidazole nitrogen of the histidine side chain together with the N-terminal amine and a backbone nitrogen, which is what distinguishes the complex from the free peptide. Published work sits in the extracellular-matrix and copper-transport literature.

How a lot is verified

Purity assayed by third-party HPLC and net content (mg per vial) measured by the lab, with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's procedures. Not for human consumption.

Also known asCopper tripeptide-1 · Copper peptide GHK-Cu · Prezatide copper · Copper(II)-GHK

GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), supplied as a lyophilized powder for laboratory research use only.

In the literature the tripeptide is studied for its copper-binding chemistry and its role in extracellular-matrix and tissue-remodelling research models; the copper ion is coordinated by the peptide backbone and the histidine side chain.

Reported mechanism · literatureDescribed in the research literature as a copper-coordinating tripeptide examined in extracellular-matrix and cytoprotection models; the summary reflects that literature only.
