Description

TB-500 — Thymosin Beta-4 Fragment

TB-500 is a synthetic fragment of the naturally occurring peptide Thymosin Beta-4 (Tβ4), specifically the actin-binding domain sequence Ac-LKKTETQ. TB-500 has been the subject of extensive preclinical research examining its role in actin sequestration, cellular migration, angiogenesis, and extracellular matrix modulation. It is one of the most frequently studied peptides in tissue repair and regeneration research.
