tb-500
TB-500 is a synthetic N-acetylated heptapeptide (Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln) corresponding to the actin-binding fragment — residues 17–23 — of thymosin β4, a naturally occurring 43-amino-acid regulatory peptide. In published preclinical literature this LKKTETQ motif has been investigated for its role in actin sequestration, cell migration, and connective-tissue repair processes in animal and in vitro models. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
A thymosin β4 fragment investigated in ACTIN-BINDING research.
