1. Product Introduction

2. 1. Product Overview

   
   
   PTD-DBM (Protein Transduction Domain-Dishevelled Binding Motif) is a high-purity, synthetic active peptide engineered for targeted biological regulation, developed through cutting-edge solid-phase peptide synthesis and multi-step purification technologies. Its molecular structure is precisely designed to ensure optimal cell penetration and specific binding affinity, delivering consistent, reproducible performance across applications.
   
   
   Visually, it appears as an off-white to white lyophilized powder with a fine, uniform texture, free from visible aggregates or impurities. With a purity of ≥98.0% (and up to 99.4% for premium grades) and an endotoxin level ≤50 EU/mg, it meets the stringent quality benchmarks of the global cosmeceutical and biotech industries. This peptide is uniquely formulated to penetrate the epidermal layer and act directly on hair follicle dermal papilla cells, offering a science-backed, targeted solution for hair growth stimulation and skin tissue repair. Its stability under typical cosmetic formulation conditions also makes it a reliable choice for long-term product development.

2. Core Functions & Mechanism of Action

• Hair Growth Promotion: PTD-DBM specifically blocks the interaction between the hair-loss-promoting protein CXXC5 and Dishevelled (Dvl), releasing the inhibitory effect on follicular development. This activates the Wnt/β-catenin pathway—a core signaling cascade for hair follicle formation—stimulating the proliferation and differentiation of hair follicle stem cells. It effectively delays follicular miniaturization, particularly in cases of androgenetic alopecia, and induces the formation of new hair follicles.
• Skin Wound Healing: By activating the Wnt/β-catenin pathway, PTD-DBM also enhances collagen synthesis and skin tissue repair, making it an effective adjuvant for accelerating wound healing and reducing scar formation.
• Synergistic Effect with Methyl Vanillate: When formulated with methyl vanillate, PTD-DBM exhibits a synergistic effect that significantly amplifies follicular activation and improves the bioavailability of the active ingredients.

3. Application Fields

• Cosmeceuticals: The primary application is in hair care products such as anti-hair loss serums, scalp repair gels, and hair growth shampoos, targeting consumers with hair loss or scalp health issues.
• Biotech Research: Used as a research intermediate in studies focused on hair follicle regeneration, wound healing, and Wnt pathway modulation.
• Custom Formulations: Ideal for compound formulations with plant extracts, vitamins, or other peptides to create high-performance hair and skin care products.

4. Packaging & Storage

• Packaging: Customization is available to meet diverse client requirements, ranging from milligram-scale vials to kilogram-grade aluminum foil bags. All packaging is double-sealed to maintain peptide activity and prevent contamination.
• Storage Conditions: For long-term stability, store in a sealed container at -20°C or below, away from light, heat, and moisture. After reconstitution, aliquot and freeze to avoid repeated freeze-thaw cycles.

5. Product Advantages

• Precise Targeting: Acts directly on the hair follicle regulatory pathway with clear, predictable efficacy and minimal off-target effects.
• High Purity & Stability: Advanced manufacturing processes guarantee consistent purity and molecular stability, reducing batch-to-batch variation.
• Versatile Application: Can be used alone or in combination with other ingredients, suitable for various product forms including serums, creams, and scalp treatments.
• Safety & Compliance: Complies with global cosmetic raw material regulations, with low endotoxin levels ensuring excellent topical safety.
