Concise research notes on the copper peptide GHK-Cu — complex chemistry, qualitative verification cues, and standard lab documentation.
The term "copper peptide" most often refers to GHK-Cu, the 1:1 complex of glycyl-l-histidyl-l-lysine with Cu²⁺. These notes cover the qualitative and analytical cues a USA research lab uses to verify a copper-peptide lot before use.
Qualitative verification cues
- Deep-blue color in aqueous solution
- UV-Vis absorbance maximum near 620 nm
- Crystalline appearance prior to reconstitution
