Description
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, supplied by Aminovera Research as a lyophilised reference material in a sealed vial. It carries CAS number 89030-95-5, molecular formula C14H22CuN6O4 and a molecular weight of 401.91 g/mol.
A metal complex, not a plain peptide
This is the only item in the catalogue that is a coordination complex rather than a peptide alone, and it behaves differently as a result. The copper centre gives the material its characteristic blue colour, and it means the analytical picture is not the same as for an uncomplexed peptide — the free tripeptide GHK carries a different CAS number (49557-75-7) and a different molecular weight. If a certificate you are comparing refers to GHK rather than GHK-Cu, it describes a different substance.
Storage differs from the rest of the catalogue
Note that this item is stored at 2–8 °C, not at -20 °C like the other materials listed here. Storage conditions are stated per product for exactly this reason. Do not apply a condition from another item in the range.
What this listing is for
The Specification tab carries the catalogue number, molecular formula, molecular weight, CAS number, composition, physical form and storage condition. The documentation panel shows whether analytical documentation has been released for the batch currently held.
Scope of supply
Supplied strictly for lawful in-vitro laboratory and analytical research. Not a medicine, not a cosmetic ingredient as supplied here, no UK marketing authorisation, and not supplied for use in humans or animals.
