Description
This vial contains a co-lyophilized research blend of two structurally and mechanistically distinct synthetic peptides — BPC-157 and TB-500 — formulated at equimolar mass ratio for investigational use in cell biology and pharmacology research contexts requiring concurrent access to both compounds.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide of 15 amino acid residues derived as a partial sequence analogue of the human gastric juice protein BPC. The compound exhibits notable aqueous stability and resistance to enzymatic degradation across a broad pH range in vitro, and has been employed as a model substrate in preclinical research examining nitric oxide (NO) system interactions, VEGF receptor signalling, and FAK-paxillin pathway activity in cell culture systems.
TB-500 is a synthetic N-terminally acetylated heptapeptide corresponding to the conserved LKKTET actin-binding motif (residues 17–23) of the full-length human Thymosin Beta-4 (Tβ4) polypeptide. As the principal G-actin sequestering domain of Tβ4, this fragment has been extensively utilized in cytoskeletal biology research to investigate actin polymerization kinetics, filamentous actin (F-actin) dynamics, and endothelial cell migration signalling cascades in vitro.
The two peptides are supplied as a single co-lyophilized blend to facilitate streamlined reconstitution in research protocols requiring both compounds. Each constituent retains its independent physicochemical identity within the blended matrix and can be verified independently via lot-specific CoA documentation.
