What is TB-500? TB-500 is a synthetic peptide fragment corresponding to amino acids 17–23 of the naturally occurring 43-amino-acid protein Thymosin Beta-4 (Tβ4). The peptide reproduces the actin-binding region of Tβ4 and has been studied in laboratory settings for its role in actin polymerization an...
