About TB-500
TB-500 is a synthetic peptide fragment derived from a segment of the Thymosin Beta-4 protein. It has been the subject of peer-reviewed preclinical research since the 1990s, with published studies examining actin sequestration, endothelial cell migration models, and connective-tissue assays across the peptide science and molecular biology literature.
All TB-500 sold by BioInfinity is manufactured by solid-phase peptide synthesis (SPPS), purified by reverse-phase HPLC, and confirmed by mass spectrometry to >99% purity. It ships as a lyophilized (freeze-dried) white powder in a septum-sealed vial (2 mg or 10 mg), ready for reconstitution with bacteriostatic water for laboratory use.
