Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1		5.5	293	CRYSTALS WERE OBTAINED WITH 4 MICROL OF RESERVOIR SOLUTION (17 % PEG 10000, 0.1 M BIS TRIS PH=5.5 AND 0.1 M AMMONIUM ACETATE), 1 MICROL. OF 1.5 MM N DODECYLPHOSPHORYLCHOLINE, AND 4 MICROL. OF PROTEIN SOLUTION. AT 293 K, CRYSTALS REACHED MAXIMUM DIMENSIONS OF 0.1 X 0.3 X 0.3 MM3 IN 15 30 DAYS., pH 5.50
