TB-500 is a synthetic fragment of thymosin beta-4, a ubiquitous actin-sequestering protein involved in cell migration, angiogenesis, and tissue repair. Research has studied its effects on recovery from musculoskeletal injury in animal models, with the Ac-SDKP tetrapeptide motif within the sequence considered central to its observed activity on endothelial cell proliferation and inflammation modulation.

Solvent Preparation

To prepare a solution, add benzyl alcohol solvent slowly along the side of the vial. Gently swirl — do not shake. Keep prepared material refrigerated. For research purposes only. Need benzyl alcohol solvent? Add it to your order.
