1VAPOR DIFFUSION, SITTING DROP6.5293SITTING DROPS WERE PREPARED BY MIXING EQUAL VOLUMES OF PROTEIN WHICH WAS 14 MG/ ML IN 20MM HEPES, PH 7.5 AND TO WHICH AN EXCESS OF SOLID INHIBITOR HAD BEEN ADDED AND RESERVOIR SOLUTION (30% PEG 2000 MONOMETHYLETHER, 0.1M SODIUM ACETATE, PH 5.0 AND 0.2M AMMONIUM SULFATE). THIS MIXTURE WAS INCUBATED OVERNIGHT AT 4C AND CENTRIFUGED TO REMOVE PRECIPITATE BEFORE SETTING UP CRYSTALLIZATION DROPS. CO-CRYSTALS WERE GROWN FROM 6 ML SITTING DROPS OF THE PROTEIN-RESERVOIR SOLUTION AND 0.3 ML OF THE RESERVOIR SOLUTION AT EITHER ROOM TEMPERATURE OR 4C, pH 6.5, VAPOR DIFFUSION, SITTING DROP, temperature 293K
