TB-500 is a synthetic fraction of the naturally occurring protein Thymosin Beta-4, which is present in virtually all human and animal cells. Specifically representing the 17-23 amino acid segment (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala), this peptide is a primary mediator of cellular migration and tissue repair. In research settings, it is studied for its ability to promote actin-binding, angiogenesis, and wound healing, making it a critical tool for investigating regenerative medicine and musculoskeletal recovery in preclinical models.
