 This study identified a new antibody fragment called VNART1, which recognizes all three forms of transforming growth factor beta, TGF. It was found to be highly specific and selective for TGF, with an affinity of 9.61 times 10 to the power of negative 8M. Additionally, it was shown to bind to key amino acids within the TGF structure, suggesting that this antibody fragment could potentially be used to treat diseases associated with excessive TGF activity.
