Description
TB-500 Research Peptide
TB-500 (Thymosin Beta-4 Fragment) is a synthetic peptide derived from the naturally occurring 43-amino acid protein Thymosin Beta-4. It retains the active region (amino acids 17-23) responsible for the actin-binding and cell migration properties that have made TB-4 one of the most studied proteins in cell biology.
TB-500’s ability to interact with actin-sequestering pathways gives researchers a focused tool for investigating cellular motility, cytoskeletal dynamics, and extracellular matrix interactions in preclinical models.
