| Description: | Citrullination assay was detected via ammonia release. PAD4 was diluted to 120 nM in assay buffer (100 mM HEPES, 50 mM NaCl, 2 mM DDT, 0.6 mg/mL BSA, pH 7.4) added to wells containing various concentration of compound or DMSO vehicle (1% final) in black 384 well plate. Following a 60-min preincubation at RT, the reaction was initiated by the addition of substrate (1.5 mM BAEE in 200 mM HEPES, 50 mM NaCl, 350 uM CaCl2, 2 mM, pH 7.4). The reaction was stopped after 60 min by addition of stop/detection buffer containing 50 mM EDTA, 2.6 mM of o-phthaladehyde and 2.6 mM DTT. Assay was incubated at RT for 90 min before measuring fluorescence's (λex 405/λem 460 nm) on Tecan reader. |
