TB500 (Thymosin B4 Acetate) 5mg

Research Peptide for Cellular Repair & Migration Studies

TB-500 (Thymosin Beta-4 Acetate) is a synthetic, 43-amino acid peptide fragment that corresponds to the active region of the naturally occurring protein Thymosin Beta-4. As a key regulator of actin polymerization and cellular motility, this research compound provides scientists with a valuable tool for investigating fundamental processes of tissue repair, wound healing, and inflammatory response at the cellular and molecular level. Supplied in its acetate salt form for enhanced stability, this lyophilized peptide is intended strictly for controlled, non-human laboratory research aimed at elucidating mechanisms of cell migration, angiogenesis, and extracellular matrix remodeling in experimental models.

Research Applications & Scientific Utility

In a laboratory setting, TB-500 enables investigation across multiple research domains related to cellular repair mechanisms. Primary applications include studying actin sequestration and cytoskeletal reorganization, modeling wound healing and tissue regeneration pathways, researching anti-inflammatory and cell-protective effects, and examining angiogenesis and endothelial cell migration. Researchers utilize this peptide to explore its role in modulating cytokines, reducing apoptosis in stressed cells, and promoting the differentiation of progenitor cells in controlled experimental models. The included documentation supports standardized application to ensure reproducible results in tissue repair research.

Laboratory Handling & Safety Protocol

• Storage: Store unopened lyophilized peptide vials at -20°C or below. Reconstituted peptide solutions should be aliquoted and stored at -20°C to -80°C to minimize degradation for short-term experimental use. The acetate formulation provides enhanced stability.

• Reconstitution: Must be performed under sterile laboratory conditions using the provided bacteriostatic water according to the included mathematical guide to achieve the desired experimental concentration (typical research concentrations range from 1-10mg/ml).

• Laboratory Safety: Standard personal protective equipment (PPE) including lab coat, nitrile gloves, and safety glasses must be worn. Follow institutional biosafety level (BSL) guidelines for handling biochemical reagents.

• Documentation: The provided CoA must be retained as part of the research record for quality assurance and publication purposes. The acetate salt form should be noted in all experimental documentation.
