TB-500 is the product name used here for full-length Thymosin Beta-4, a naturally occurring 43-amino-acid polypeptide represented by the sequence Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH.
Thymosin Beta-4 is widely studied as a major intracellular G-actin-sequestering peptide. Its interactions with monomeric actin and its conserved actin-binding region make it an established research tool for investigating cytoskeletal organization, actin dynamics, and cell migration.
Published research has also examined full-length Thymosin Beta-4 in endothelial-cell migration, angiogenesis models, myoblast chemotaxis, dermal repair models, skeletal-tissue models, and other cellular systems involving migration and extracellular responses.
The commercial term TB-500 has been used inconsistently in scientific and analytical literature. Some materials identified as TB-500 have contained a shorter acetylated thymosin beta-4 fragment corresponding to residues 17-23. The specifications presented on this page refer specifically to the full-length 43-amino-acid Thymosin Beta-4 form.
BioVault Labs supplies TB-500 in a 10 mg lyophilized research format with ≥99% HPLC-verified purity. The product is third-party tested, and available Certificate of Analysis documentation may be requested directly from our team.
