Discovery of new selenoureido analogs of 4-(4-fluorophenylureido) benzenesulfonamides as carbonic anhydrase inhibitors
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 8.3 281 concentrated CA II at about 10 mg/mL was set up in SD-2 plates with the following ratio of protein plus reservoir plus seeds: 250nL plus 225 nL plus 25 nL. The plate was incubated at 8C and the reservoir condition consisted of 2.9 M ammonium sulfate with 0.1 M Tris buffer at pH 8.
