Research applications
TB-500 is a synthetic fragment of thymosin beta-4 containing the conserved actin-binding (LKKTETQ) domain. It is studied in cell migration, endothelial cell tubule formation, wound-healing, anti-inflammatory, and tissue-repair research models. As a lyophilized research peptide it is supplied for actin-dynamics and regenerative biology studies, with sequence verification by mass spectrometry.
