GHK-Cu

Copper-Binding Tripeptide for Connective Tissue & Regenerative Research

GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine that declines with age. This small, stable peptide (molecular weight: 401.9 Da) forms a characteristic blue-colored complex when bound to copper ions (Cu²⁺). In research settings, GHK-Cu serves as a powerful tool for investigating multiple biological processes, including the upregulation of collagen and elastin synthesis, modulation of antioxidant enzymes (SOD, catalase), promotion of wound healing and tissue remodeling, and influence on gene expression related to tissue repair. Supplied as a distinctive blue lyophilized powder, this research-grade complex we intend strictly for controlled, non-human laboratory studies exploring the mechanisms of skin regeneration, anti-inflammatory responses, and connective tissue homeostasis in experimental models.

Complete Research Kit Contents & Verification

Each research order provides a complete experimental package designed for standardized research in dermatology and tissue engineering:

• Primary Research Compound: 10 sterile glass vials containing 50mg of lyophilized GHK-Cu peptide complex per vial, presenting as a characteristic light blue to turquoise powder.

• Reconstitution Solution: 30ml vial of sterile Bacteriostatic Water (0.9% Benzyl Alcohol), essential for creating stable peptide solutions for experimental use.

• Laboratory Administration Tools: Pack of sterile 1ml insulin syringes (29G x 1/2″) for precise measurement and transfer in accordance with research protocols.

• Sterilization Supplies: Individually wrapped alcohol prep swabs to maintain aseptic technique during vial handling and reconstitution.

• Research Protocol Documentation:

  • Dosing Schedule: Standardized administration protocol for common research models focusing on dermatological applications, wound healing studies, and connective tissue research.

  • Usage Instructions: Comprehensive guide covering reconstitution math, storage conditions (stable at room temperature but -20°C recommended for long-term), handling safety, and experimental best practices for topical or systemic research applications.

• Quality Verification: Certificate of Analysis (CoA) provided with each batch, detailing:

  • Peptide Purity (>98% by HPLC)

  • Copper Content Analysis (Theoretical: ~15.8% by weight; Verified by ICP-MS or colorimetric assay)

  • Identity Confirmation (Mass Spectrometry for peptide; AAS/ICP for copper)

  • Sterility Testing Results

  • Endotoxin Levels (<10 EU/mg)

  • Absorbance Spectrum Confirmation (Characteristic peak ~254nm for copper complex)

  • Residual Solvent/Moisture Analysis

  • Color Verification (Blue complex indicates proper chelation)

Research Applications & Scientific Utility

In a laboratory setting, GHK-Cu enables investigation across multiple research domains related to tissue regeneration and protection. Primary applications include studying collagen types I, III, and IV synthesis in fibroblast and keratinocyte cultures, researching elastin production and elastic tissue remodeling, investigating antioxidant and anti-inflammatory mechanisms in skin models, exploring wound healing acceleration and reduced scarring in animal models, and examining hair follicle growth and cycling in dermatological research. Researchers utilize this copper-peptide complex to explore its unique dual role as both a signaling molecule (via peptide sequence) and a copper delivery system, which together influence multiple genes involved in tissue repair, inflammation, and oxidative stress response.

Laboratory Handling & Safety Protocol

• Storage: Store unopened lyophilized GHK-Cu vials in a cool, dry place. For long-term stability (>1 year), storage at -20°C we recommend. Reconstituted solutions are stable for several weeks when refrigerated at 2-8°C, protected from light.

• Reconstitution: Must be performed under standard laboratory conditions. The blue powder readily dissolves in bacteriostatic water or saline to form a clear blue solution. Gentle swirling is sufficient.

• Laboratory Safety: Standard personal protective equipment (PPE) including lab coat, nitrile gloves, and safety glasses we recommend. While GHK-Cu has low acute toxicity in research models, copper is a heavy metal and you should handle with appropriate respect in the laboratory.

• Visual Quality Control: The characteristic blue color is a key indicator of proper copper chelation. Loss of blue color may indicate degradation or copper dissociation.
