GHK-Cu, often called copper peptide, is a naturally occurring copper-binding tripeptide (Gly-His-Lys) found in human plasma. It is used in fibroblast and keratinocyte culture to study extracellular matrix protein expression and skin cell biology, and NuVion stocks it in Australia in 50mg and 100mg vials.
- Copper(II) complex of the tripeptide Gly-His-Lys
- Used in fibroblast and keratinocyte culture models
- Applied in matrix protein and gene expression assays
- Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry
GHK-Cu structure and research use
GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine. The bound copper ion gives the lyophilised powder its blue colour. In the laboratory it is used in fibroblast and keratinocyte models for work on collagen and other extracellular matrix proteins and on gene expression. It is also one of the peptides in the GLOW and KLOW blends.
GHK-Cu vial sizes and prices, 50mg and 100mg
NuVion stocks GHK-Cu in 50mg and 100mg vials. Both hold the same lyophilised peptide, and the 100mg vial works out cheaper per milligram.
| Vial size | Price | Price per mg | Availability |
|---|---|---|---|
| GHK-Cu 50mg | $49.00 | $0.98 | In stock |
| GHK-Cu 100mg | $89.00 | $0.89 | In stock |
GHK-Cu research applications
- Fibroblast and keratinocyte cultures read for collagen, glycosaminoglycan and decorin synthesis and MMP-2, TIMP-1 and TIMP-2 secretion
- Copper coordination studies by UV-visible spectroscopy, EPR, potentiometric titration and copper exchange experiments with albumin
- Boyden chamber and transwell chemotaxis assays using monocytes, mast cells or endothelial cells
- Gene expression profiling by qPCR or RNA sequencing in cultured cells, including NF-kB reporter assays
