About TB-500
TB-500 is a synthetic version of thymosin β4, a 43-amino-acid protein found in most mammalian cells. Thymosin β4 binds monomeric actin, and it has been studied for decades as one of the main actin-sequestering peptides in the cell.
Canada Research Labs supplies TB-500 as 10mg of lyophilized powder in a 3 mL glass vial, packed and shipped from Ontario. This product is full-length synthetic thymosin β4, not a shorter fragment.
See our TB-500 research overview and the comparison BPC-157 vs TB-500.
Research background
Thymosin β4 was characterized as an actin-sequestering peptide in the early 1990s, and much of the later research builds on that role in cytoskeletal organization and cell migration. A frequently cited study by Bock-Marquette and colleagues (Nature, 2004) reported that thymosin β4 activates integrin-linked kinase and influences cardiomyocyte migration and survival in mouse models.
Other preclinical work has examined thymosin β4 in models of angiogenesis, wound repair and inflammation. Products sold as "TB-500" vary between suppliers, and some are short fragments rather than the full 43-amino-acid sequence. Researchers comparing results with published studies should confirm which form they are using against the certificate of analysis.
