Description
TB-500 is a synthetic peptide based on the active region of thymosin beta-4 (Tβ4), a naturally occurring actin-binding protein. In research it is studied for its role in regulating actin polymerization, cell migration, and cytoskeletal dynamics, processes central to wound-healing and tissue-remodeling models. Supplied for in-vitro and laboratory research only — not for human or veterinary use.
