Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 6.6 293 N9 crystals were grown by hanging drop vapour diffusion against a reservoir of 1.9M potassium phosphate, pH 6.8, starting with equal volumes of N9 NA(10-15mg/ml in water) and potassium phosphate buffer 1.4M KH2PO4:3M K2HPO4 in ratio 8:4, pH 6.6 at 20 degrees celsius. Inhibitor complexeswere obtained by soaking N9 crystals in a solution of 1.4M potassium phosphate buffer, pH 6.8, containing 5 mM of inhibitor for 3 hours at 18 degrees celsius. Glycerol cryo-buffer also soaked in.
