Assay Method Information

Assay Name:  hFAP Binding Assay
Description:  Table 1B: Compounds were tested in a direct binding assay using 8K surface plasmon resonance biosensor (GE Healthcare) at 20° C. Immobilization of hFAP (M39-A757) on a CMD200M sensor chip (Xantec) was performed using standard amine coupling procedure in immobilization buffer (10 mM HEPES, 150 mM NaCl, 0.05% Tween20, pH 7.4). The surface was washed with 10 mM NaOH, 1M NaCl before being activated with EDC/NHS (GE Healthcare), followed by immobilization of hFAP (in 10 mM Acetate pH 5.0). Finally, the surface was deactivated by ethanolamine. Immobilization levels of hFAP were around 4000-6000 RU. The reference spot was treated as described, omitting the injection of hFAP. Compound concentration series were injected over the immobilized protein in increasing concentrations (2-500 nM) using single cycle kinetics in running buffer (20 mM TRIS, 150 mM NaCl, 0.05% Tween20, 1% DMSO, pH 7.4). Interaction models were fitted globally to the experimental traces, enabling determination of kon, koff and Kd.
