The A2 bi-specific inhibitor exhibits similar biochemical activity as the two mono-specific H3 (DR3) and pTACE inhibitors. (A) Binding of A2 to TL1A in comparison to the mono-specific H3 protein. Binding analysis was performed by ELISA using plates that were pre-coated with TL1A (see Section Materials and Methods for detailed description). (B) Inhibition of TACE by A2 in comparison to the mono-specific pTACE inhibitor. Inhibition of TACE activity was assessed using a fluorogenic peptide substrate DEVD-AMC.
