Compound notes
TB-500 is the synthetic form of Thymosin Beta-4, a 43-amino acid peptide first isolated from calf thymus tissue in the 1960s. It has the molecular formula C212H350N56O78S, a molecular weight of 4,963.4 g/mol, and is identified by CAS number 77591-33-4. The peptide is notable for containing a central actin-binding domain, a region structurally complementary to actin, a major structural protein found in biology. Thymosin Beta-4 is classified as a naturally occurring intracellular peptide and is one of the most abundant members of the beta-thymosin family. TB-500 is supplied as a white to off-white lyophilized powder, soluble in water, and should be stored frozen for long-term stability. This product is strictly for research purposes only.
