Description
TB-500 is the commercial name commonly used for a synthetic peptide related to Thymosin Beta-4 (TB4), a naturally occurring 43-amino-acid actin-binding protein. Vials sold as “TB-500” may contain either the full-length Thymosin Beta-4 sequence (molecular formula C212H350N56O78S, molecular weight approximately 4963.5 g/mol, CAS 77591-33-4) or a shorter active fragment, depending on the supplier and batch; the specific content should be confirmed against the certificate of analysis for this product.
Research on Thymosin Beta-4 and its fragments has examined their role in actin monomer sequestration, cellular migration signaling, and angiogenic pathways in cell culture and animal models.
Supplied as a lyophilized powder for reconstitution, each batch is analyzed by HPLC to confirm purity.
For laboratory research use only. Not for human or veterinary use, and not intended for diagnostic or therapeutic application.
