TB-500

TB-500 is a synthetic research peptide corresponding to the biologically active region of Thymosin Beta-4, a naturally occurring 43-amino acid peptide encoded by the TMSB4X gene. It is extensively studied in regenerative biology, cellular migration, angiogenesis, and tissue remodeling research due to its involvement in actin regulation and cellular movement.

TB-500 has become an important research compound for investigating how cells migrate, organize, and respond to tissue injury under controlled laboratory conditions. Scientific literature has explored its interaction with cytoskeletal proteins, endothelial cells, inflammatory signaling pathways, and extracellular matrix remodeling, making it valuable across a broad range of in vitro and preclinical research models.

Supplied as a sterile lyophilized powder, TB-500 is intended exclusively for laboratory and scientific research applications. Every production batch undergoes independent third-party analytical testing to help ensure purity, identity, and consistency for reliable experimental use.
