Overview

AHK-Cu is a copper(II) complex of the tripeptide alanine-histidine-lysine, structurally related to GHK-Cu. The histidine imidazole and N-terminal amine coordinate the Cu²⁺ ion.

It is used in laboratory research on copper–peptide coordination, copper delivery to cultured cells, and dermal papilla and fibroblast cell-culture models. No claims are made regarding effects in humans or animals.

Typical in-vitro applications

• Copper–peptide coordination and stability studies
• Dermal papilla and fibroblast cell-culture assays
• Extracellular-matrix gene-expression studies in vitro
