The peptide is best known in research for its central actin-binding domain — a region structurally complementary to actin, one of the most common structural proteins in biology — which underlies its study as a regulator of G-actin sequestration and cytoskeletal dynamics.\u003c\/p\u003e\n\u003cp\u003eIn published research, TB-500 \/ thymosin β4 has been investigated in cell and animal models for roles in cell migration, angiogenesis and tissue-repair signalling. The peptide adopts a largely unstructured, flexible conformation in solution, which is thought to support its interaction with actin. These findings derive from laboratory and preclinical studies and do not establish any effect in humans.\u003c\/p\u003e\n\u003cp\u003eThis product is intended solely as a reference material for \u003cem\u003ein vitro\u003c\/em\u003e and laboratory research conducted by qualified professionals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote on TB-500 forms:\u003c\/strong\u003e The name \"TB-500\" is used in the research market for two distinct materials — the full-length 43-amino-acid thymosin β4 peptide, and the shorter N-acetylated active fragment Ac-LKKTETQ (residues 17–23).
