What it is
TB-500 is a synthetic peptide corresponding to an active region of thymosin beta-4, an actin-binding protein. It is classed as a thymosin beta-4-related regenerative peptide. It is supplied as lyophilized material for research use only.
Mechanism (technical)
TB-500 and thymosin beta-4 have been studied for actin binding and association with cell migration, angiogenesis, and tissue-repair signaling. These mechanisms have been investigated in preclinical wound and injury models. The molecular pathways are described across review and animal literature.
