Product Overview

PTD-DBM is a cell-penetrating synthetic peptide engineered to investigate the Wnt/β-catenin intracellular signaling cascade. It functions by inhibiting CXXC5, a negative regulator of this pathway, making it a compelling research tool for scientists studying regenerative biology, dermal papilla cell behavior, and follicular miniaturization mechanisms. Researchers have used PTD-DBM to explore how targeted pathway modulation may influence cellular outcomes in controlled in vitro and in vivo experimental models. Direct Anti Peptide makes this compound available for sale to verified research institutions and licensed laboratory professionals.

Peptide Structure & Amino Acid Sequence

PTD-DBM is a chimeric peptide composed of two functional domains: a protein transduction domain (PTD) derived from a cell-penetrating sequence, fused to a DBM (Dishevelled-binding motif) segment that competitively disrupts the CXXC5–Dishevelled protein–protein interaction. This dual-domain architecture enables efficient intracellular delivery of the inhibitory motif without the need for transfection reagents, making it a practical tool for membrane-permeable pathway intervention studies. The precise sequence engineering underpins its selectivity and utility in Wnt/β-catenin research contexts.

Purity & Analytical Verification (HPLC & MS)

Every vial of PTD-DBM peptide supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. High-performance liquid chromatography (HPLC) is used to confirm peptide purity at ≥98%, ensuring that the active compound is free from synthesis by-products, truncated sequences, and residual reagents. Mass spectrometry (MS) analysis independently verifies the molecular weight and confirms structural integrity of the final product. Researchers can rely on these dual verification methods as a foundation for reproducible experimental outcomes.

Quality Control & Lyophilization Integrity

PTD-DBM is produced under controlled synthesis conditions and subjected to multi-stage quality control protocols. The lyophilization process is performed under validated freeze-drying parameters to preserve the peptide’s native conformation, biological activity in research models, and long-term stability. Each sterile glass vial is sealed under inert atmosphere to prevent moisture ingress and oxidative degradation. This approach ensures that researchers receive a product that maintains consistent characteristics from batch to batch, supporting reliable and reproducible laboratory work.

Safety, Handling & Laboratory Precautions

PTD-DBM Peptide Vial is intended exclusively for use by trained research professionals operating within appropriately equipped laboratory environments. Standard laboratory personal protective equipment (PPE) — including gloves, lab coat, and eye protection — should be worn when handling lyophilized peptide material. This compound is not approved for any human or animal administration and must not be used outside of a controlled research setting. All handling, storage, and disposal must comply with applicable institutional biosafety protocols and local regulatory requirements.

Reconstitution, Packaging & Storage

PTD-DBM arrives lyophilized in a sealed sterile glass vial, ready for reconstitution by qualified laboratory personnel using appropriate research-grade solvents as determined by the experimental protocol. Reconstitution procedures must be performed under aseptic conditions in a suitable laboratory environment. Prior to reconstitution, the lyophilized vial should be stored at −20°C in a dry, dark environment, away from repeated freeze-thaw cycles. Once reconstituted, aliquot and store according to standard peptide handling practices to maintain integrity. Refer to institutional SOPs for specific reconstitution guidance.

Intended Research Use & Market Positioning

PTD-DBM is positioned as a premium research-grade peptide for scientists investigating Wnt/β-catenin pathway dynamics, CXXC5 protein interactions, hair follicle regeneration biology, and cellular transduction mechanisms. Its cell-penetrating design makes it particularly valuable in studies requiring intracellular delivery of inhibitory peptide sequences without viral or chemical transfection methods. Direct Anti Peptide offers PTD-DBM for sale to academic institutions, pharmaceutical research teams, and independent research laboratories seeking high-purity, analytically verified peptide tools.
