TB-500

TB‑500 is a synthetic peptide based on the active region of thymosin beta‑4, designed for controlled experimental use in studies focused on actin‑binding behaviour, cellular migration, and cytoskeletal organisation. It serves as a research analogue for examining how thymosin beta‑4–related sequences influence structural and motility‑associated cellular processes. In biochemical and cell‑based research systems, peptides derived from thymosin beta‑4 are evaluated for their ability to interact with G‑actin, affecting actin polymerisation and broader cytoskeletal remodelling. The responses observed in experimental models vary according to peptide concentration, exposure time, cell type, and overall study design.
