Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	2.5	277	1 UL OF 1 MM PROTEIN IN 5 MM BISTRIS, PH 6.5, 2 MM DTT WAS ADDED TO 1 UL OF 0.1 M SODIUM CITRATE, PH 2.5, 1.5 M AMMONIUM SULFATE. THE MIXTURE WAS INCUBATED AT 4 DEGREE CENTIGRADE IN A HANGING DROP SETUP. CRYSTALS GREW IN A FEW DAYS AND WERE CRYO-PROTECTED BY SHORT SOAKING IN 0.1 M SODIUM CITRATE, PH 2.5, 1.5 M AMMONIUM SULFATE, 25% (V/V) GLYCEROL.
