Axon Biolabs supplies the GHK-Cu copper tripeptide standard ($\text{Cu}^{2+}$) as an analytical-grade copper-chelated peptide complex. Structured as Glycyl-L-histidyl-L-lysine bound to a copper(II) ion, this deep blue compound offers high purity for sensitive testing. Furthermore, researchers widely evaluate this complex in biochemical studies examining extracellular matrix (ECM) regulation, collagen gene expression, and metal ion transport mechanisms.
This chelated GHK-Cu copper tripeptide standard provides researchers with a stable reference material for comparative analysis against non-chelated short peptides like our KPV tripeptide standard. Specifically, investigators analyze structural stability variations during cellular exposure. Additionally, it serves as a benchmark compound in cellular longevity assays alongside coenzymes like our NAD+ coenzyme standard. As a result, research teams can effectively map complex signal transduction pathways.

Storage & Reconstitution Guidelines
Store dry powder at -20°C in a desiccated, light-protected container to safeguard compound stability. Furthermore, technicians should reconstitute the material in sterile analytical water or neutral aqueous buffers under clean-room conditions. However, due to its copper-chelated structure, personnel must avoid exposure to strong chelating agents (e.g., EDTA) in stock solutions. Therefore, avoiding these additives prevents unwanted metal ion displacement during testing.
Quality Verification
Our quality control team analyzes each production lot by HPLC for peptide purity and atomic absorption spectroscopy (AAS) to verify correct copper stoichiometry. Specifically, our specialists cross-reference ingredient entries with the COSING European Commission Database. Therefore, researchers can easily access analytical certificates via our online compliance center.
