For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

PTD-DBM is a cell-penetrating peptide derived from the DBM (Dishevelled-binding motif) domain, engineered to modulate the Wnt/β-catenin signaling pathway. This pathway plays a foundational role in cellular differentiation, tissue homeostasis, and follicular morphogenesis. Research interest in PTD-DBM has grown substantially due to its demonstrated capacity to stimulate dermal papilla cell activity, promote hair follicle neogenesis, and support regenerative biological processes in controlled laboratory models. Direct Anti Peptide supplies this compound in a convenient nasal spray delivery format, purpose-built for non-invasive research administration studies.

Peptide Structure & Amino Acid Sequence

PTD-DBM is a synthetic fusion peptide combining a protein transduction domain (PTD) with a DBM-derived sequence designed to competitively inhibit the CXXC5–Dvl interaction. This inhibition activates downstream Wnt signaling cascades implicated in progenitor cell recruitment and follicular regeneration. The peptide’s cell-penetrating properties allow researchers to study intracellular pathway modulation without requiring viral vectors or invasive transfection methods, making it a valuable tool in molecular biology and dermatological research.

Purity & Analytical Verification (HPLC & MS)

Every batch of PTD-DBM Nasal Spray supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to dispatch. High-performance liquid chromatography (HPLC) confirms compound purity at ≥98%, while mass spectrometry (MS) validates molecular identity and structural integrity. These dual verification methods ensure that researchers receive a compound of consistent, reproducible quality suitable for peer-reviewed investigation. Certificates of Analysis (CoA) are available upon request and accompany all orders.

Quality Control & Lyophilization Integrity

The active peptide component of PTD-DBM is produced under strict quality control protocols, including lyophilization to preserve long-term structural stability. Lyophilized peptides resist degradation from moisture, oxidation, and temperature fluctuations during transit and storage. The nasal spray format is prepared under controlled conditions to maintain peptide activity and formulation consistency across research batches. Direct Anti Peptide’s quality assurance process ensures batch-to-batch reproducibility for reliable experimental outcomes.

Safety, Handling & Laboratory Precautions

PTD-DBM Nasal Spray is intended exclusively for use by trained research scientists operating within appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times when handling this compound. Researchers should wear appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coats. This product must not be administered to humans or animals under any circumstances. All handling, storage, and disposal must comply with applicable institutional biosafety guidelines and local regulatory requirements.

Reconstitution, Packaging & Storage

PTD-DBM Nasal Spray is supplied in a ready-to-use spray format for research convenience. The product should be stored at 2–8°C upon receipt and protected from direct light and repeated freeze-thaw cycles to preserve formulation integrity. Researchers undertaking reconstitution studies should follow validated laboratory protocols using sterile, research-grade solvents. Unused portions should be stored according to institutional chemical management policies. Shelf life and stability data are detailed in the accompanying CoA documentation.

Intended Research Use & Market Positioning

PTD-DBM is actively investigated across multiple research domains, including dermatological science, regenerative medicine, and molecular signaling studies. Key areas of laboratory inquiry include androgenetic alopecia models, hair follicle neogenesis, cutaneous wound healing, collagen and elastin biosynthesis, and the broader role of Wnt pathway modulation in tissue homeostasis.
