Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 7.5 292 A PROTEIN SAMPLE, LYOPHILIZED AFTER HPLC PURIFICATION FROM TFA/ACETONITRILE MIXTURE, WAS DISSOLVED IN WATER TO A CONCENTRATION OF 9 MG/ML. 2 UL DROPS OF THE PROTEIN SOLUTION WERE MIXED WITH 2 UL OF RESERVOIR SOLUTION CONTAINING 2% PEG 400, 2 M AMMONIUM SULFATE AND 0.1 M NA HEPES, PH 7.5. THE HANGING DROPLETS WERE EQUILIBRATED AT 19 DEG C THROUGH THE GAS PHASE WITH THE RESERVOIR. PRISMATIC CRYSTALS MEASURING UP TO 0.4 MM GREW WITHIN 12 HOURS.
