[ COMPOUND.PROFILE ]

What Is Thymosin Beta-4?

Thymosin Beta-4 (TB4) is a 43-amino acid peptide with the molecular formula C212H350N56O78S and a molecular weight of approximately 4921 Da. It is the most abundant member of the beta-thymosin family, a group of highly conserved peptides found in virtually all nucleated mammalian cells. First isolated from thymus tissue, Thymosin Beta-4 is now recognized as a ubiquitous intracellular peptide present at concentrations of 100-500 microM in most cell types, with...
