GHK-Cu (Glycyl-L-histidyl-L-lysine + Cu²⁺) is a reference tripeptide copper complex, naturally present in human plasma. Its concentration in biological samples decreases with age, making it a frequently cited subject in academic dermatological and gerontological literature. This material is supplied as a lyophilized reference standard for in-vitro laboratory studies.
Investigated Biochemical Pathways (academic context)
-
Extracellular matrix gene expression: in-vitro models of collagen I, III, and IV expression modulation; studies of matrix metalloproteinase (MMP) activity in fibroblast cultures.
-
Cell proliferation: in-vitro models of fibroblast and keratinocyte proliferation at controlled concentrations.
-
Epigenetic signaling: academic studies of changes in gene expression profiles in dermal cell lines.
-
Antioxidant assays: the copper complex is the subject of in-vitro studies of its interaction with reactive oxygen species and redox systems.
Laboratory Use and Storage
Suitable as a reference standard for HPLC quantification of copper complexes and in-vitro cell assays. In laboratory practice, the lyophilized powder is reconstituted with sterile diluents, such as Bacteriostatic Water - 10 ml. To preserve the integrity of the molecule, it is recommended to store the solution in the dark and at a stable low temperature (2-8 °C) after reconstitution, with an optimal environment of -20 °C for long-term stability of the research sample.
Product Purpose
This material is sold exclusively as a reference standard for laboratory and in-vitro research, biochemical analysis, and educational purposes. It is not intended for human consumption, therapeutic use, skin application, ingestion, inhalation, or veterinary purposes. It is not a drug, dietary supplement, cosmetic, or medical device.
Access
Sales are subject to age verification (18+) and declaration of research or collector's purpose upon order completion.
