AHK-CU | Copper-Binding Tripeptide Complex

Vascular Endothelial & Extracellular Matrix Research

AHK-Cu (Alanine-Histidine-Lysine Copper) is a synthetic metal-binding tripeptide complex commonly referenced in localized vascular signaling, endothelial cell proliferation, collagen pathway synthesis, and follicular cellular model research.

In plain terms: AHK-Cu is used in lab research to study how copper peptides stimulate blood vessel network growth and cell proliferation in connective tissue models.

Description

  • AHK-CU

    AHK-CU — Ala-His-Lys chelated to copper(II) (CAS 145438-82-0) — is a synthetic copper–tripeptide complex studied as a model scaffold for copper-dependent biological signaling in skin biology and extracellular matrix (ECM) research. It is supplied as a laboratory-grade lyophilized powder intended strictly for analytical and non-clinical research applications.

    Copper(II) coordination via the histidine imidazole and terminal amine of the AHK tripeptide confers the complex with distinct redox and metallopeptide properties compared to the non-chelated GHK sequence. Researchers use AHK-CU in fibroblast and keratinocyte in vitro models to examine copper-dependent collagen synthesis pathway activation, SOD-mimetic oxidative stress responses, and ECM remodeling assays where copper bioavailability is a controlled variable.

    COMMON RESEARCH APPLICATIONS

    Collagen Synthesis Pathway Research
    AHK-CU is used in dermal fibroblast models to study copper-dependent stimulation of collagen I and III gene expression, pro-collagen processing enzyme activity (LOX, PAD), and ECM matrix deposition assays.

    Oxidative Stress & SOD-Mimetic Assays
    The copper chelate is examined in H₂O₂ challenge and ROS detection models in keratinocytes to assess copper-mediated antioxidant pathway modulation and SOD-like radical scavenging activity.

    ECM Remodeling Studies
    Used in scratch assay and fibroblast contraction models to study AHK-CU effects on MMP/TIMP balance, fibronectin deposition, and integrin-mediated signaling in wound-environment matrices.

    Comparative Copper-Peptide Screening
    Benchmarked alongside GHK-Cu and other copper-chelated peptides to characterize structure-activity relationships in copper coordination geometry and downstream ECM pathway selectivity.

    • What is this product?
      AHK-CU (CAS 145438-82-0, MW 397.88 g/mol) is a synthetic copper(II)–tripeptide complex (Ala-His-Lys) supplied as a lyophilized blue-green powder for laboratory research use only. It serves as a model copper-peptide tool compound for ECM and skin biology signaling research.
    • What purity and testing methods are used?
      Each lot is tested by reverse-phase HPLC to ≥98% purity, with MS confirmation of peptide identity and ICP analysis to verify copper stoichiometry. A lot-specific COA is included with every order, accessible via QR code on the label.
    • What are the key chemical identifiers?
      CAS 145438-82-0 · Molecular formula C₁₄H₂₂CuN₆O₄ · MW 397.88 g/mol · Synonyms: Ala-His-Lys copper(II), Copper tripeptide AHK, Cu-AHK.
    • What signaling pathways does AHK-CU address in research models?
      AHK-CU is studied in collagen synthesis pathway models (LOX, PAD enzyme activity), oxidative stress response assays (copper-mediated SOD-mimetic activity), and ECM remodeling research (MMP/TIMP balance). It is examined in fibroblast and keratinocyte cell lines as a model for copper–peptide ECM interactions.
    • How is AHK-CU reconstituted for research use?
      Dissolve in sterile water or PBS (pH 7.0) at ~5 mg/mL. Use immediately or aliquot and store at −80°C. Avoid repeated freeze-thaw cycles and protect from light to prevent copper-peptide complex degradation.
    • What is the recommended storage upon receipt?
      Store immediately at −20°C desiccated. Short-term at 2–8°C is acceptable for up to 2 weeks. The copper chelate is sensitive to moisture and light; inspect vials for colour integrity (blue-green) upon receipt.
    • What is a COA and why does it matter?
      A COA documents lot-specific purity (HPLC ≥98%), peptide identity (MS), copper content (ICP), and appearance. Each lot ships with a QR-accessible COA. Review before use to confirm identity, purity, and copper stoichiometry meet your experimental requirements.
