GHK-Cu Copper Tripeptide Lyophilized Peptide Powder, Research Grade

GHK‑Cu, also known as Copper Tripeptide‑1, is a metal‑peptide chelate complex. It consists of three amino acids: glycine, histidine and lysine linked by peptide bonds, and forms a stable complex through chelation with copper(II) ions. The product is manufactured via solid‑phase peptide synthesis (SPPS), purified by reversed‑phase liquid chromatography, desalted and finally lyophilized into loose blue powder. Lyophilization greatly improves storage stability of this peptide complex and reduces risk of molecular degradation, suitable for laboratory storage and sample preparation.

This substance is peptide‑type research intermediate for in‑vitro tests of research institutes and laboratories only. All information on this page only describes basic material data including synthesis route, chemical structure, physicochemical property and storage condition. No description of in‑vivo biological activity, pharmacological effect, skincare or health‑care function is included. No implication for biological in‑vivo application effect.

Product Name: GHK‑Cu ‑ Alias: GHKCu, Copper Tripeptide‑1

Amino Acid Sequence: H‑Gly‑His‑Lys‑OH · Cu(II) ‑ Short Sequence: Gly‑His‑Lys (GHK) ‑ Molecular Formula: C₁₄H₂₂CuN₆O₄ ‑ Molecular Weight: 401.91 Da ‑ Synthesis Method: Solid‑Phase Peptide Synthesis (SPPS) ‑ Purification: Reversed‑Phase High Performance Liquid Chromatography (RP‑HPLC) ‑ Appearance: Blue to blue‑purple loose lyophilized powder ‑ Structural Feature: 1:1 chelation between tripeptide ligand and copper(II) ion to form stable coordination complex

Solubility: Good water solubility. Soluble in sterile water and deionized water, stable in aqueous solution with suitable pH value; poorly soluble in most non‑polar organic solvents.

1. Stability: Lyophilized solid powder has better stability than prepared aqueous solution. Aqueous solution of copper peptide complex is sensitive to temperature, pH and light. Long‑term storage may lead to substance variation. It is recommended to prepare solution before experiment rather than long‑time storage.
2. Purity Option: HPLC ≥98% and HPLC ≥99% are available for selection. Each batch comes with independent COA certificate and HPLC chromatogram. MS mass spectrometry data can be supplied on request.

Vial packaging: 10mg /50mg /100mg vacuum lyophilized sealed vials. ‑ Bulk supply: Bulk powder above gram scale is available, custom package can be negotiated according to customer laboratory requirements. ‑ Vial label: Only material code, batch No. and net weight printed. No marking related to human application or finished product efficacy.

Long‑term storage: Keep powder sealed at ‑20℃ under dry and dark environment, avoid repeated freeze‑thaw cycles.

1. Short‑term storage: Unopened product can be stored at 2‑8℃ in cool and dark place.
2. Prepared solution: Copper peptide aqueous solution should be kept under low temperature and used for in‑vitro experiment promptly; long‑term preservation is not recommended.
3. Protection note: Minimize long‑time exposure of powder under room‑temperature air, strong light and high humidity environment, to prevent moisture absorption and structural change of complex.

This substance is for in‑vitro laboratory scientific research only, handled by qualified research personnel. Strictly forbidden for direct or indirect human / animal in‑vivo usage. Shall not be used as drug, pharmaceutical raw material, food or dietary supplement.
