TB-500

Technical Overview TB-500 is a synthetic acetylated peptide fragment corresponding to the active region of thymosin beta-4. In biochemical research settings, this peptide is frequently investigated for its role in actin-binding interactions and peptide-mediated signaling pathways in vitro. TB-500 is synthesized and purified to research-use analytical standards suitable for controlled laboratory investigation. This material is prepared using established synthesis and purification methods, with purity assessed by HPLC to a level suitable for research and assay use. Its lyophilized (freeze-dried) powder in a sealed research vial format supports stable handling, storage, and preparation in controlled scientific environments.
