Overview of GHK-Cu (Glycyl-L-Histidyl-L-Lysine: Copper)
GHK-Cu is a naturally occurring human copper-binding tripeptide known for its high affinity for copper(II) ions. First isolated from human plasma, GHK-Cu is extensively studied for its roles in tissue remodeling, antioxidant defense, collagen and elastin synthesis, and gene expression modulation.
Key Biological Pathways & Research Findings
-
Extracellular Matrix (ECM) Synthesis: Upregulates collagen I, collagen III, elastin, and proteoglycans in dermal and connective tissue models.
-
Antioxidant & Anti-Inflammatory Signaling: Suppresses pro-inflammatory cytokines while elevating superoxide dismutase (SOD) activity.
-
DNA Repair & Gene Expression: Modulates expression of multiple human genes, resetting cell signaling toward regenerative states.
Reconstitution & Laboratory Preparation
-
Reconstitution: Reconstitute with Bacteriostatic Water. Ensure complete dissolution prior to experimental assay.
-
Purity Verification: High-Performance Liquid Chromatography (HPLC) is essential to verify copper chelation stability and peptide purity.
Frequently Asked Questions
Why is copper chelation important in GHK-Cu?
The distinct blue color confirms stable copper(II) ion binding, which is essential for its biological activity and structural integrity.
