Product Overview

TB500 Nasal Spray is a peptide-based intranasal formulation that mirrors the biological activity of thymosin beta-4, a naturally occurring polypeptide. Thymosin beta-4 is widely studied for its roles in cell migration, tissue remodeling, angiogenesis, and inflammatory modulation. The nasal spray format allows delivery across the nasal mucosa, providing researchers with a convenient and reproducible administration route for in-vitro and controlled in-vivo research models. This product is for sale exclusively for laboratory and research purposes and must not be used in humans, animals, or any clinical setting.

Peptide Structure & Amino Acid Sequence

TB500 is a synthetic analogue of the active region of thymosin beta-4, a 43-amino-acid protein endogenous to mammalian tissue. The active fragment studied most extensively is the actin-binding domain, which is understood to mediate the peptide’s core biological properties in research contexts. The intranasal formulation encapsulates this peptide sequence within a buffered aqueous solution optimized for mucosal compatibility, ensuring structural integrity from manufacture through delivery to the researcher.

Purity & Analytical Verification (HPLC & MS)

Every batch of TB500 Nasal Spray supplied by Direct Anti Peptide undergoes rigorous high-performance liquid chromatography (HPLC) analysis to confirm purity at ≥98%. Mass spectrometry (MS) is additionally employed to verify the correct molecular weight and sequence identity of the active peptide component. Certificates of Analysis (CoA) are available upon request and accompany all orders, giving researchers full traceability and confidence in the material they are working with. This analytical commitment is central to our quality promise and makes our product a trusted choice for researchers who buy TB500 online.

Quality Control & Lyophilization Integrity

While the nasal spray format is supplied as a ready-to-use aqueous solution rather than a lyophilized powder, Direct Anti Peptide applies equivalent quality control standards across all production stages. The peptide active ingredient used in formulation is sourced as a lyophilized intermediate with verified moisture content and residual solvent levels below accepted thresholds. Final formulation batches are subject to sterile filtration, endotoxin screening, and container closure integrity testing prior to release, ensuring that the spray reaching our customers meets research-grade specifications.

Safety, Handling & Laboratory Precautions

TB500 Nasal Spray is strictly a research reagent. It must be handled exclusively by trained laboratory professionals in appropriately equipped research environments. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and a lab coat — should be worn at all times when handling this material. The product must not be self-administered, administered to animals outside approved research protocols, or used in any clinical or diagnostic context. Researchers should consult applicable institutional biosafety guidelines before use.

Reconstitution, Packaging & Storage

TB500 Nasal Spray is supplied as a pre-formulated, ready-to-use intranasal solution requiring no reconstitution. The metered-dose spray pump delivers a consistent volume per actuation, supporting reproducible dosing in research protocols. Store the product at 2–8°C (refrigerated) and protect from direct light and freezing. Do not use beyond the indicated expiry date printed on the packaging. All materials should be handled and disposed of in accordance with institutional and local regulatory guidelines for research chemicals.

Intended Research Use & Market Positioning

TB500 Nasal Spray is intended for use in laboratory research investigating peptide-mediated tissue repair, angiogenesis, cellular migration, central nervous system (CNS) recovery models, and inflammatory pathway modulation. The intranasal delivery route makes it a valuable tool in studies where mucosal absorption kinetics are a variable of interest. Direct Anti Peptide positions this product for academic institutions, pharmaceutical research organizations, and independent laboratories seeking a high-purity, analytically verified TB500 formulation available for sale at a competitive price point.
