TB-500

TB-500 (Thymosin Beta-4 Fragment) is a synthetic analog of the naturally occurring 43-amino acid peptide Thymosin Beta-4 (Tβ4), which plays a critical role in cell migration, proliferation, and differentiation. TB-500 represents the active region responsible for actin sequestration and tissue repair signaling.
