TB-500 5mg is the standard research vial of full-length Thymosin Beta-4 in the Peptide Sciences catalog, offering a practical working quantity for multi-week preclinical studies.
TB-500 Mechanisms Studied in the Lab
The central active region of thymosin beta-4, including the LKKTETQ actin-binding motif, is responsible for much of its activity in experimental models. Studies describe up-regulation of cell-migration pathways, reduced inflammatory cytokine expression and support for new capillary formation. Researchers often pair it with BPC-157 to investigate whether the two peptides act on complementary stages of tissue repair.
