Description
TB-500 is a synthetic peptide based on the active region of thymosin beta-4, a protein involved in cell structure and movement. It is used in laboratory work on cell migration, blood vessel formation and tissue repair models. Supplied as a lyophilized powder, strictly for laboratory research and analytical use.
Intended use · In-vitro laboratory research only. Not for human or animal consumption, and not for clinical, diagnostic, cosmetic or personal use.
N° 002 · How It Works
How TB-500 works.
TB-500 copies the part of thymosin beta-4 that binds actin, the protein cells use as internal scaffolding. By binding actin it affects how cells change shape and move, which is why it turns up in studies of cell migration. Research on thymosin beta-4 has looked at wound repair, the growth of new blood vessels, and heart tissue after injury. One thing worth being clear about: almost all of that work studies the full protein, not the shorter TB-500 sequence.
