X-RAY DIFFRACTION 8.5 293 Sample of human Chymase in 50 mM MES/NaOH pH 5.5, 150mM NaCl, 1mM TCEP, 10% Glycerol) at a concentration of 11mg/ml to 14mg/ml.Add [2-[(4-methylpyridin-2-yl)amino]-2-oxoethyl] 2-methylquinoline-4-carboxylate at 10x molar ratio. The compound helps to obtain crystals but is not visible in the structures. Add 0.5 mM ZnCl2. Add inhibitor, incubate for 16h on ice. Crystallize using microbatch setups with Al's oil (Hampton Research), with total drop size 1ul with 50% protein sample, using crystallization reagent of 0.1M Tris/HCl pH 8.5, 0.2M NaCl, 25% PEG 3350.
