| Description: | Final top concentration of compound in the assay is 50 μM. Final assay conditions were as follows:Reaction volume: 26 μlAssay buffer: 25 mM hepes, pH 7.5, 5 mM NaCl, 1 mM DTT, 0.2 mg/ml BSA, 0.01% CHAPS, 50 μM Calcium, and 5 μM TPENFinal concentrations: 5 nM hPAD4 enzyme, 250 μM BAEE, and 0.5% DMSOTotal incubation time: 30 mins compound and enzyme preincubation at 37° C., 90 min enzyme/substrate reaction, 30 min reaction with phenyl glyoxal at 37° C.Stop solution: 40 μl 5% TCA in ACN0.13 μL of compound solution was added to 13 μL of 10 nM PAD4 in assay buffer. After 30 min 13 μl of 500 μM of BAEE was added in 25 mM hepes, pH 7.5, 5 mM NaCl, 1 mM DTT, 0.2 mg/ml BSA, 0.01% CHAPS, 50 μM Calcium, 5 μM TPEN was added and the reaction incubated for 90 min at 37° C. The enzymatic reaction was quenched by addition of 15 μl of 6.1N TCA, 100% Final Concentration is 20%, 35 μl of 8.5 mM phenyl glyoxal (final concentration 4 mM) is then added and the reaction is incubated for 30 min at 37° C. |
