Thymosin beta-4 is the major intracellular G-actin sequestering peptide; research links its release at injury sites to enhanced cell migration, blood-vessel formation and reduced scar formation in dermal, corneal and cardiac injury models.
TB4 regulates the actin pool required for cells to migrate into a wound, linking this mechanism across its repair studies.
Preclinical myocardial-infarction studies reported thymosin beta-4 associated improvements in cardiomyocyte survival and vascular growth, prompting early-phase clinical exploration in cardiac repair.
Mouse studies of cardiac repair are among the most cited TB4 research, though clinical translation remains early.
TB-500 is the research designation for synthetic thymosin beta-4, a 43-amino-acid actin-binding peptide present in nearly all mammalian cells. It is sold strictly for laboratory research use — not for human or veterinary use.
The catalog specification lists 99.38% HPLC purity. Our testing policy also requires independent endotoxin, heavy-metals and sterility screening. The current certificate table and linked PDF are samples; a production certificate must match the batch ID printed on the vial.
TB-500 (TB4) (10mg vials) is offered in 20mg, 50mg, 100mg boxes (2 × 10mg vials, 5 × 10mg vials, 10 × 10mg vials), priced $130.00 to $490.00 — the per-mg cost falls as box size increases.
Keep sealed lyophilized vials refrigerated at 2–8°C away from light (stable 24+ months). After reconstitution with bacteriostatic water, refrigerate and use within the study-validated window, typically 30 days; never freeze reconstituted solution.
