Research Grade Glycyl-L-Histidyl-L-Lysine Copper Complex Synthetic Peptide Raw Powder CAS 67727-97-0

Product Overview

GHK‑Cu, CAS No. 67727-97-3, is a synthetic copper-binding short-chain polypeptide compound prepared via standardized solid-phase peptide synthesis and metal complex chelation purification routes. The raw material is refined by multi-gradient reversed-phase high performance liquid chromatography to obtain uniform blue lyophilized powder. All synthesis, purification, split filling and sealing processes are completed in dust-free closed constant-temperature workshops. Each batch undergoes strict HPLC purity testing, residual impurity analysis, heavy metal limit inspection and comprehensive microbial screening before delivery, ensuring consistent batch quality and repeatable experimental data.

This GHK‑Cu lyophilized powder is only supplied as biochemical peptide intermediate raw material for in-vitro academic laboratory scientific research exclusively. It is strictly limited to basic cell biological experiments and intracellular metal ion signal pathway research in universities and biomedical research institutions. Any application related to human epidermal repair, wrinkle reduction, anti-aging cosmetic raw materials, facial care formulations, external topical preparations and human skin administration is completely prohibited. All production and packaging specifications are customized to meet laboratory research demands for life science keratinocyte molecular mechanism analysis.

The finished product presents fine blue lyophilized powder with uniform texture, no caking, no discoloration and no visible foreign particles. The HPLC purity is steadily maintained at 99%. Trace unreacted amino acid raw materials, inorganic salts and synthetic chelation byproducts are controlled at ultra-low levels, which will not bring extra interference to in-vitro human keratinocyte cell model research, intracellular copper ion transport correlation experiments and epidermal molecular signal transduction detection, guaranteeing accurate and stable experimental test results.

Core Product Advantages

1. Excellent Physicochemical Stability The chelated copper-polypeptide structure features high structural stability and strong anti-hydrolysis performance under sealed low-temperature storage. The valid experimental storage period can reach 24 months under standard refrigeration. Aluminum cap sealed vial packaging effectively isolates moisture absorption, oxidation and ultraviolet damage during cross-border transportation, maintaining stable physical and chemical properties for laboratory test use.
2. Outstanding Aqueous Solubility The lyophilized polypeptide raw material dissolves rapidly and completely in conventional laboratory neutral aqueous solvents including purified water and PBS buffer. No insoluble particles, precipitation or suspended residues exist after dissolution. Researchers can prepare multiple concentration gradients flexibly according to different experimental protocols, suitable for cell incubation, liquid chromatographic detection and various biochemical reaction tests.
3. Ultra-Low Interference Impurities Multi-stage gradient HPLC purification thoroughly removes synthetic peptide precursors, residual metal ions and inorganic impurities. The ultra-low impurity content eliminates negative interference on cell morphology observation, intracellular metal signal pathway exploration and biochemical reaction verification, significantly reducing experimental error values and improving data repeatability.
4. Flexible Customized Packaging Specifications We provide diversified customized packaging for laboratory trial tests and long-term batch research experiments. All storage vials are sealed with professional butyl rubber stoppers and aluminum flip caps to achieve excellent air tightness and prevent sample hydrolysis deterioration. Custom bulk packaging service is available for institutional research laboratories.

Standard Storage Instructions

1. Short-term Temporary Storage (Within 3 Months) Keep the reagent vial tightly sealed, store in a cool dry environment away from strong light, and preserve under 2°C~8°C refrigeration condition. Reduce frequent opening operations to avoid moisture absorption and polypeptide chelate decomposition.
2. Long-term Storage (More Than 3 Months) Complete secondary sealing of the container and store stably at -20°C constant low temperature. Repeated freezing and thawing must be avoided to prevent molecular structural changes and attenuation of experimental biological activity.
3. Post-dissolution Storage Rules The prepared aqueous experimental solution must be fully used within 7 days under 2°C~8°C refrigeration. Waste liquid shall be disposed of in accordance with laboratory biochemical waste management standards to avoid solution deterioration and microbial contamination.
