TB-500

About TB-500

TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring 43-amino-acid protein involved in regulating the actin cytoskeleton — the scaffolding that lets cells move and change shape. It is one of the most frequently cited peptides in tissue-remodelling research.

Research groups use TB-500 in laboratory models examining cell migration, wound-healing dynamics, and inflammatory signalling in vitro and in small-animal studies. It is commonly ordered by laboratories running comparative peptide research programs.

Every Pickering Peptides lot is third-party tested by HPLC and mass spectrometry at 99%+ purity before it ships. Vials arrive sealed as a lyophilized (freeze-dried) powder from our Ontario, Canada facility, and every order includes the batch report key so you can verify the lab results directly with the testing laboratory.
