Product Overview

GHK-Cu — biochemically classified as Glycyl-L-Histidyl-L-Lysine copper(II) complex — is a naturally occurring carrier tripeptide that has attracted significant scientific interest across regenerative biology, dermatological research, and cellular survival studies. Its defining characteristic is the stable coordination of a copper(II) ion (Cu²⁺) within the tripeptide backbone, enabling researchers to investigate localized copper bioavailability, enzymatic cofactor dynamics, and tissue-remodeling mechanisms under controlled in vitro conditions. The Peptide Store supplies GHK-Cu as a high-purity lyophilized vial, providing biochemistry, molecular biology, and dermatological laboratories with a standardized, ultra-pure baseline reagent.

Peptide Structure & Amino Acid Sequence

GHK-Cu is a tripeptide composed of three amino acid residues in the following sequence: Glycine – L-Histidine – L-Lysine, complexed with a divalent copper ion (Cu²⁺). The histidine residue plays a pivotal role in metal coordination, forming a stable square-planar chelate geometry with the copper center. This structural configuration is central to the peptide’s recognized function as a copper transport and delivery vehicle in research models. The molecular formula of the free peptide base is C₁₄H₂₄N₆O₄, and the copper complex carries the CAS registry number 49557-75-7. The molecular weight of the copper complex is approximately 340.38 g/mol.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu 50mg offered for sale at The Peptide Store is independently verified to a minimum purity of ≥98% using reverse-phase high-performance liquid chromatography (RP-HPLC). Complementary mass spectrometry (MS) confirmation validates the precise molecular identity and copper complexation integrity of each lot. These dual analytical checkpoints ensure that researchers receive a chemically consistent, research-grade reagent with full traceability across experimental replicates.

Quality Control & Lyophilization Integrity

GHK-Cu is produced under stringent quality control protocols and lyophilized under controlled conditions to preserve structural integrity, copper coordination stability, and long-term biochemical activity. Lyophilization eliminates residual moisture, significantly extending shelf life and reducing degradation risk during transport and storage. Each vial is sealed under inert atmosphere to prevent oxidative interference with the Cu²⁺ center, ensuring the reagent arrives in optimal condition for immediate laboratory deployment.

Safety, Handling & Laboratory Precautions

GHK-Cu 50mg is a research-grade chemical reagent and must be handled exclusively by trained laboratory personnel in accordance with institutional safety protocols. Appropriate personal protective equipment (PPE), including nitrile gloves, laboratory coat, and eye protection, should be worn at all times during handling. Avoid inhalation of lyophilized powder. This compound is not approved for any biological, clinical, or consumptive application. All waste disposal must comply with applicable local, national, and institutional chemical waste regulations.

Reconstitution, Packaging & Storage

GHK-Cu 50mg is packaged in a sterile, sealed glass vial with lyophilized powder ready for laboratory reconstitution using appropriate research-grade solvents as defined by your experimental protocol. Reconstitution should be performed under aseptic conditions using validated laboratory techniques. Once reconstituted, aliquot into single-use volumes to avoid repeated freeze-thaw cycles. Store the intact lyophilized vial at −20°C for long-term preservation. Reconstituted solutions should be stored at 4°C and used within a timeframe consistent with your validated stability data.

Intended Research Use & Market Positioning

GHK-Cu is widely utilized in peer-reviewed research contexts examining collagen synthesis regulation, superoxide dismutase (SOD) cofactor dynamics, lysyl oxidase (LOX) activity, extracellular matrix remodeling, and cellular survival signaling pathways. It represents one of the most studied copper carrier peptides in modern dermatological and regenerative biology research. The Peptide Store positions GHK-Cu 50mg as an accessible, premium-grade tool for academic institutions, contract research organizations (CROs), and independent research laboratories seeking the best price without compromising analytical quality.
