TB-500 is a synthetic peptide corresponding to a biologically active region of thymosin beta-4 (Tb4), a naturally occurring actin-sequestering protein. TB-500 is used as a reference compound in cytoskeletal-biology and tissue-repair research.
Thymosin beta-4 is a 43-amino-acid protein; TB-500 refers to a shorter synthetic fragment associated with its actin-binding region. Researchers should note the distinction between full-length thymosin beta-4 and the TB-500 fragment when comparing literature.
In vitro and in animal studies, this peptide has been investigated for its role in actin sequestration, cell migration, and angiogenesis markers. These findings are confined to laboratory and preclinical research and are not statements about human outcomes.
Supplied lyophilized. Store at -20°C. Reconstitution with bacteriostatic or sterile water is common for laboratory handling. Refrigerate reconstituted solution and use it within the appropriate protocol window.
Identity is confirmed by mass spectrometry and purity is determined by HPLC. Each batch ships with a batch-specific certificate of analysis from an independent third-party laboratory; refer to the COA for lot-specific values. Endotoxin and sterility testing are not performed unless stated.
