TB-500 is a synthetic research peptide derived from Thymosin Beta-4, a naturally occurring 43-amino acid protein found in virtually all mammalian cell types. Thymosin Beta-4 was originally isolated from the thymus gland and identified as a key regulator of actin dynamics, playing a central role in cytoskeletal organization, cell migration, and tissue repair signaling.
