GHK-Cu, the Cu(II)-coordinated complex of the tripeptide glycyl-L-histidyl-L-lysine, supplied by BioFusion as a sealed, amber-shielded 3 mL research pen containing 100 mg for copper-peptide research chemistry.
Research context
GHK-Cu is one of the most-cited copper-coordination complexes in peptide research. The pen presents the pre-formulated complex at 100 mg in a light-protected 3 mL research format, with the intact Cu(II) coordination giving the characteristic blue color (lambda-max about 525 nm).
Formulation & documentation
Each pen is filled from lots produced by solid-phase peptide synthesis in a U.S.-based ISO 9001:2008 facility and verified for identity (LC-MS), purity (reverse-phase HPLC-UV ≥99.0%), moisture (Karl Fischer), and counter-ion (ion chromatography) before formulation. The pre-measured 3 mL research pen is filled and sealed under controlled conditions.
Storage & handling
Store the sealed pen refrigerated at 2-8 °C and protect from light; avoid freeze-thaw cycling. As a pre-formulated liquid pen it requires no reconstitution. Handle as a laboratory reference material.
Why BioFusion
Copper-peptide formulations frequently ship under- or over-loaded when suppliers skip ion-chromatography stoichiometry checks. BioFusion verifies copper stoichiometry and ≥99.0% peptide purity before filling. Bulk discounts trigger at three+ units; members save 25% on every order plus complimentary U.S. shipping for 365 days.
For research and laboratory use only. This product is not a drug, food, or cosmetic, and is not intended for diagnostic, therapeutic, or in vivo human use.
Keep lyophilized until needed.
Store the lyophilized vial cool and dry, away from light, until your protocol calls for it. In freeze-dried form the material stays stable for extended bench storage.
Reconstitute as needed with the diluent your method specifies, then keep the prepared solution refrigerated and use it within your validated window.
