Actin-binding peptide

Research use only
TB-500 is the research designation for a synthetic fragment of thymosin beta-4, most often the acetylated heptapeptide Ac-LKKTETQ. Thymosin beta-4 is an actin-sequestering protein studied as a regulator of cytoskeleton dynamics. The fragment is supplied here as a lyophilized research material, not as a medicine or sports product.
Laboratory work places TB-500 / thymosin beta-4 fragments in tissue-repair biology: cell migration, angiogenesis models, and remodeling after injury in muscle, tendon and cardiac preparations. Published literature examines actin binding, cell motility and repair signaling across dermal, musculoskeletal and cardiovascular models. These are research territories, not outcomes a visitor should expect.
