TB-500 is a synthetic peptide corresponding to the 17-amino acid active region (Ac-SDKP sequence) of Thymosin Beta-4, a naturally occurring 43-amino acid protein. While the full-length Thymosin Beta-4 molecule has broad biological activity, TB-500 retains the key actin-binding domain that drives research interest in cell migration and tissue biology. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.4% avg across published reports). Key research areas: Cell migration and tissue remodeling Actin-binding and cytoskeletal dynamics Cardiac tissue biology and cellular signaling Important distinction: TB-500 is a fragment of Thymosin Beta-4, not a synonym for it. Full-length Thymosin Beta-4 (43 aa) has broader systemic activity, while TB-500 (17 aa) retains the active actin-sequestering region. For research purposes only. Not for human consumption.
