About

The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), a sequence that occurs naturally and binds copper. Also listed as prezatide copper. Its solutions are a distinctive deep blue.

In the literature

Cited in cell-culture literature on fibroblast behaviour, collagen turnover and extracellular-matrix remodelling.

Storage

Store the sealed vial at −20 °C, protected from light and moisture; copper complexes are photosensitive and should stay shielded. Let it reach room temperature before opening.

Supplied as

Questions

What is GHK-Cu?
The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), a sequence that occurs naturally and binds copper. Also listed as prezatide copper. Its solutions are a distinctive deep blue.
What does 50 mg on the GHK-Cu vial mean?
The label states the total quantity in the vial: 50 mg of lyophilized powder. Solara does not publish whether that figure is the gross powder weight or the net peptide content.
What is the molecular weight of GHK-Cu?
PubChem lists an average molecular weight of 402.92 g/mol and the formula C14H23CuN6O4+ (PubChem CID 71587328). This is a computed reference value for the compound, not a measurement of a Solara lot. The label does not state the salt form; a salt has a higher formula weight than this value.
What is the CAS number of GHK-Cu?
The CAS Registry Number given for GHK-Cu in its PubChem record is 89030-95-5; other salt forms carry other numbers.
How should GHK-Cu be stored?
Store the sealed vial at −20 °C, protected from light and moisture; copper complexes are photosensitive and should stay shielded. Let it reach room temperature before opening.
Where does Solara ship GHK-Cu from?
Solara ships from Canada. Orders are dispatched within one to two business days of payment, sealed and packed to keep the powder dry and out of light. Prices are in Canadian dollars. Shipping is $15 flat per order, and free on orders over $200.
Is Solara's GHK-Cu for human use?
No. The GHK-Cu Solara supplies is a lyophilized powder for laboratory research use only, not for human or veterinary use. This product is not an authorized drug, carries no Drug Identification Number and is not GMP material. The Research use policy states the full condition of supply.
