About TB-500 (Thymosin Beta-4)
TB-500 is a synthetic peptide corresponding to the active fragment of Thymosin Beta-4, a naturally occurring actin-binding protein involved in cell migration and cytoskeletal regulation. The fragment retains the region associated with cell motility and is widely used as a research tool for studying regenerative cellular processes.
In laboratory research, TB-500 is examined in models of tissue repair, angiogenesis, cell migration, and flexibility-related recovery. It is supplied as a lyophilized powder for reconstitution under controlled conditions, verified at ≥98% purity with a certificate of analysis available on request. This product is offered for research use only and is not intended for human application.
