Description
AHK-CU (Copper Tripeptide-3)
AHK-Cu, also known as Copper Tripeptide-3, is a high-purity synthetic complex consisting of the tri-peptide L-Alanyl-L-Histidlyl-L-Lysine chelated with a copper (II) ion. While structurally similar to the well-known GHK-Cu, the specific amino acid sequence of AHK-Cu grants it unique biological affinities, particularly within vascular endothelial cells and dermal papilla cells. In the landscape of dermatological and regenerative research, AHK-Cu is an essential experimental tool for investigating the stimulation of hair follicle growth, the synthesis of type I collagen, and the regulation of vascular endothelial growth factor (VEGF). It provides researchers with a targeted model to study the reversal of follicular miniaturization and the enhancement of localized microcirculation.
Our AHK-Cu is synthesized in an ISO 9001:2015 certified environment using precision liquid-phase peptide synthesis and controlled chelation. We achieve an ultra-high chemical purity of ≥99%, ensuring a stable and potent complex. The product is characterized by its signature vibrant blue color and high aqueous solubility, offering the reliability and reproducibility required for high-fidelity cellular assays and tissue engineering studies.

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the AHK-Cu powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and protects the copper-peptide complex from premature degradation during storage.
Superior Chelation Stability
Our synthesis protocol ensures that the copper ions are securely bound to the AHK sequence, preventing ion dissociation and ensuring consistent bioactivity across all research applications.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the AHK-Cu cake is at the base.
-
Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is a clear, transparent blue.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 14 days for optimal potency.
