GHK-CU

### GHK-Cu (Glycyl-L-histidyl-L-lysine Copper) GHK-Cu is a naturally occurring tripeptide-copper complex originally isolated from human plasma, now synthesized for rigorous in-vitro investigation. In laboratory settings, GHK-Cu is studied primarily for its high affinity for divalent copper (Cu2+), acting as a specialized carrier peptide that facilitates the cellular uptake of copper—a critical cofactor for numerous enzymatic processes. The biochemical profile of GHK-Cu is defined by its ability to modulate the expression of an extensive array of genes, particularly those associated with the remodeling of the extracellular matrix (ECM). Research indicates that the complex may influence the activity of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs), suggesting a regulatory role in the synthesis and degradation of collagen and elastin fibers within cellular scaffolds. At the molecular level, GHK-Cu is a subject of intense interest regarding its potential to influence various signal transduction pathways. Preclinical models have explored its impact on the TGF-beta signaling pathway and its ability to stimulate the proliferation of fibroblasts and keratinocytes in vitro. Furthermore, investigators utilize GHK-Cu to study antioxidant mechanisms, as the complex has demonstrated the capacity to quench lipid peroxidation products and reduce the production of free radicals in managed laboratory environments. Its role in modulating inflammatory markers—specifically by influencing the expression of pro-inflammatory cytokines such as IL-1 and TNF-alpha—remains a cornerstone of its pharmacological evaluation in cellular biology. For laboratory applications, GHK-Cu is typically provided as a lyophilized powder to ensure maximum structural integrity. It is highly soluble in aqueous solutions, including bacteriostatic water or phosphate-buffered saline (PBS). Once reconstituted, the solution should be aliquoted and stored at -20°C or -80°C to prevent degradation, while the lyophilized form may remain stable at room temperature for short durations during transit. To maintain the stability of the copper-peptide bond, researchers should avoid exposing the compound to extreme pH levels or high temperatures. **This compound is strictly for in-vitro research and laboratory use only; it is not intended for human or veterinary diagnostic or therapeutic applications.**
