TB 500

B-500 is a synthetic peptide fragment corresponding to the active region of thymosin beta-4, a 43-amino acid protein that is one of the most abundant intracellular peptides in mammalian cells. Specifically, TB-500 encompasses the actin-binding domain of thymosin beta-4, centered around the sequence LKKTETQ, which has been demonstrated to play a pivotal role in actin polymerization dynamics and cytoskeletal organization in cell biology research. The interaction of TB-500 with G-actin monomers provides researchers with a precise molecular tool for manipulating the actin polymerization equilibrium.

In laboratory settings, TB-500 has been extensively studied for its effects on cellular migration, with wound healing scratch assays and transwell migration experiments consistently demonstrating enhanced motility of endothelial cells, keratinocytes, and corneal epithelial cells upon exposure to this peptide. Researchers have also investigated the influence of TB-500 on endothelial tube formation assays and matrigel angiogenesis models, reporting dose-dependent increases in tubulogenesis parameters. Additional areas of investigation include effects on inflammatory mediator expression, metalloproteinase activity, and the balance between pro- and anti-inflammatory cytokine profiles in immune cell culture systems.
