Assay Method Information

Assay Name:  hFAP Inhibition Assay (Tight Binders)
Description:  Table 1: Compounds were tested in a biochemical inhibition assay using human Fibroblast activation protein alpha (hFAP) enzyme at 2.4 pM FAC (Proteros, 38-760 (PR-0071) and the substrate Ala-Pro-AMC (ARI-3144) at 20 μM FAC. 384 low volume black plates (Greiner #784076) were used. 4 μL, 4.8 pM enzyme solution (100 mM Tris HCl, 100 mM NaCl, 0.05% Chaps, pH 7.4) was added to 40 nL compounds (in DMSO) at 10 CR, 3 fold dilution series from 50 nM FAC. Plates were incubated for 15 min at rt in dark. 4 μL, 40 μM substrate solution (100 mM Tris HCl, 100 mM NaCl, 0.05% Chaps, pH 7.4) was added to each well. Plates were centrifuged at 1000 rpm and incubated for 2.5 h at rt in dark. The plates were read on a PHERAstar reader with excitation 340 nm and emission 460 nm. Data were analyzed in Genedata Screener .
