About TB-500
TB-500 is a synthetic analog of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid peptide present in high concentrations in blood platelets, wound fluid, and various tissues throughout the body. TB-500 corresponds to the active fragment of Thymosin Beta-4 (residues 17-23, sequence Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln), which retains the key biological activities of the full-length protein.
Thymosin Beta-4 plays a crucial role in actin regulation and cell migration processes. Research indicates TB-500 promotes angiogenesis through upregulation of vascular endothelial growth factor (VEGF) and modulation of endothelial cell migration. Studies have examined its effects on extracellular matrix remodeling, inflammation resolution, and stem cell differentiation in various tissue types.
A unique property of TB-500 is its ability to cross cellular membranes due to its small size and structure, allowing direct intracellular effects on actin dynamics. This makes it particularly valuable for studying intracellular cytoskeletal regulation in research models.
Pure Pharm Peptides' TB-500 is verified at 99.793% purity, one of the highest purity scores in our recovery peptide lineup.
