📖 What is Pal-AHK (Palmitoyl Tripeptide-3)?

Pal-AHK is a synthetic lipopeptide consisting of three amino acid residues—Alanine, Histidine, and Lysine (AHK) —covalently conjugated to a palmitoyl (C16:0) fatty acid chain. This structural design serves two critical research functions:

1. Copper-Binding Capacity: The tripeptide sequence AHK, structurally related to the well-characterized GHK peptide, possesses inherent affinity for divalent copper ions (Cu²⁺). This copper-peptide complex is hypothesized to be the bioactive form responsible for modulating cellular behaviors including proliferation, migration, and differentiation.
2. Enhanced Membrane Interaction: The lipophilic palmitoyl moiety substantially increases the peptide’s hydrophobicity, promoting intercalation into lipid bilayers and potentially enhancing residence time within cellular membranes or tissue microenvironments. This modification addresses a fundamental limitation of unmodified hydrophilic peptides in biological research systems.

The primary research function of Pal-AHK centers on its investigated role as a signaling molecule in angiogenesis and hair follicle biology. Specifically, the peptide has been studied for its potential to:

• Stimulate neovascularization by promoting endothelial cell proliferation, migration, and tubule formation
• Activate dermal papilla cells, the specialized fibroblasts within hair follicles responsible for regulating the hair growth cycle
• Modulate growth factor expression, including vascular endothelial growth factor (VEGF), fibroblast growth factors (FGFs), and hepatocyte growth factor (HGF)
• Support extracellular matrix remodeling during tissue repair and regeneration

It is critical to emphasize that Pal-AHK is supplied strictly for non-human, in vitro and ex vivo laboratory experimentation. It is not a pharmaceutical compound, cosmetic ingredient, or dietary supplement, and is expressly prohibited for human or animal consumption, injection, topical application, or any diagnostic or therapeutic use.

Precision in research demands precision in reagents. Below is the complete analytical profile for our Pal-AHK (Palmitoyl Tripeptide-3), verified through independent, third-party laboratory analysis.

🔬 How Does Pal-AHK Work? Investigating Mechanisms in Angiogenesis & Hair Follicle Biology

Understanding the proposed mechanism of action for Pal-AHK requires integration of copper biology, growth factor signaling, and lipid-mediated cellular interactions. While the complete pharmacodynamic profile remains under active investigation, current scientific literature supports several interconnected hypotheses:

1. Copper-Dependent Signaling Complex Formation:

The AHK tripeptide sequence exhibits high affinity for copper(II) ions, forming a stable tripeptide-copper complex. This complex is hypothesized to be the biologically active species. Copper itself is an essential cofactor for angiogenesis, serving as a cofactor for enzymes including superoxide dismutase and cytochrome c oxidase, and has been demonstrated to stabilize hypoxia-inducible factor-1α (HIF-1α), a master transcriptional regulator of VEGF.

2. Growth Factor Upregulation:

In multiple experimental models, copper-binding peptides have been shown to upregulate the expression and secretion of key angiogenic growth factors, particularly:

• Vascular Endothelial Growth Factor (VEGF): Primary driver of endothelial cell proliferation and vascular permeability
• Fibroblast Growth Factor-2 (FGF-2): Mitogen for fibroblasts and endothelial cells
• Hepatocyte Growth Factor (HGF): Regulator of cell scattering, morphogenesis, and angiogenesis
• Transforming Growth Factor-Beta (TGF-β): Modulator of extracellular matrix synthesis and wound repair

3. Dermal Papilla Cell Activation:

In hair follicle research, Pal-AHK is investigated for its effects on dermal papilla cells, the specialized mesenchymal cells within the hair bulb that constitute the primary signaling center regulating hair follicle cycling. Dermal papilla cell activation, proliferation, and secretion of paracrine factors are critical for anagen (growth phase) initiation and maintenance. Copper peptides have been reported to prolong dermal papilla cell survival and maintain their inductive properties in culture.

4. Extracellular Matrix Remodeling:

Pal-AHK may influence the synthesis and organization of extracellular matrix components, including collagen, fibronectin, and proteoglycans. This activity is particularly relevant to wound healing research and dermal regeneration models.

5. Membrane-Mediated Signaling:

The palmitoyl chain facilitates interaction with lipid rafts and may promote receptor clustering, internalization, or activation of membrane-associated signaling cascades independent of classical receptor binding.

Your experimental design should test specific hypotheses regarding these or alternative mechanisms. Appropriate controls—including unmodified AHK peptide, copper sulfate alone, and known angiogenesis inducers (VEGF, FGF-2)—are essential for rigorous mechanistic interpretation.

❓ Frequently Asked Questions (FAQs)

Q: What is the difference between Pal-AHK and GHK-Copper?

A: While both are copper-binding tripeptides, they are structurally distinct. GHK-Copper (Glycyl-Histidyl-Lysine) is the most extensively studied copper peptide, with sequence Gly-His-Lys. Pal-AHK (Alanyl-Histidyl-Lysine) substitutes glycine with alanine at the N-terminus and is typically palmitoylated. These structural differences may influence copper affinity, receptor interactions, and membrane partitioning. Comparative studies represent a legitimate and active area of research.

Q: Is copper required for Pal-AHK activity in my assays?

A: This is an empirical question central to your research. The prevailing hypothesis is that the copper-peptide complex is the bioactive species. Some investigators pre-complex Pal-AHK with equimolar copper sulfate before addition to culture. Others add copper to the culture medium separately. Controls should include peptide alone, copper alone, and peptide + copper to isolate effects.

Q: What concentration range is typically studied?

A: Optimal concentrations are assay-dependent and must be empirically determined. Based on published literature for related copper peptides and preliminary reports for Pal-AHK, initial dose-response experiments typically span 1 nM to 100 µM. Factors influencing optimal concentration include cell type, receptor expression, assay duration, and specific endpoint (e.g., proliferation, tubule formation, gene expression).

Q: How should I reconstitute Pal-AHK for cell culture?

A: Due to its palmitoyl modification, direct aqueous solubility is limited. We recommend:
1) Centrifuge the sealed vial briefly (3,000-5,000 rpm, 1-2 minutes)
2) Reconstitute in high-purity, anhydrous DMSO to prepare a concentrated stock (e.g., 10-50 mM)
3) Vortex gently and warm to 37°C if necessary to achieve complete dissolution
4) Dilute this stock 1:1000 or greater into pre-warmed cell culture medium
5) Maintain final DMSO concentration ≤ 0.1% to avoid cytotoxicity
6) Do not store diluted peptide in culture medium; prepare fresh for each experiment

Q: How do I access the Certificate of Analysis (COA)?

A: The COA is available for immediate download from the product page by entering your vial’s unique batch/lot number. This document provides the actual HPLC chromatogram with integrated purity percentage, the MS spectrum with observed molecular ion peak, and the quantitative purity assignment. A physical copy is also included with your shipment.

Q: Is Pal-AHK stable in solution?

A: No. Lyophilized Pal-AHK stored at -20°C is stable for up to 24 months. However, once reconstituted in DMSO or other solvents, stability decreases substantially. For optimal results:

• Prepare fresh stock solutions for critical experiments
• Store stock solutions at -80°C if they must be kept
• Never subject stock solutions to repeated freeze-thaw cycles
• Never store diluted working solutions in aqueous media

Q: Can Pal-AHK be used in topical formulation research?

A: Yes, for in vitro formulation development studies only. Investigators frequently incorporate Pal-AHK into research-grade topical vehicles to study lipopeptide stability, release kinetics, and penetration through synthetic membranes or ex vivo human skin models. These studies are conducted exclusively in the laboratory and do not involve human or animal application.

Q: Do you offer bulk quantities or custom synthesis?

A: Yes. Please contact our technical consultation team to discuss bulk peptide requirements, custom vial sizes, related copper-binding peptide sequences, or palmitoylated peptide analogs. We are equipped to support research programs requiring specialized peptide synthesis and supply arrangements.
