TB-500

TB-500 is a synthetic peptide fragment corresponding to the active region of Thymosin Beta-4, a naturally occurring 43-amino acid protein present in virtually all human and animal cells. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only.

Research Context
TB-500 is studied in in-vitro and animal-model research for its association with the upregulation of actin-binding protein expression and the actin-sequestering pathway. In these research settings it is examined in connection with cell migration, proliferation, and differentiation, as well as inflammatory-mediator signalling, angiogenesis-associated pathways, and extracellular matrix remodelling. These molecular targets make it a subject of interest in cytoskeletal, actin-pathway, and skeletal muscle research. This information is provided for research context only and does not describe any effect in humans or animals.
