Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.5		THE PROTEIN WAS CRYSTALLIZED BY THE SITTING DROP METHOD WITH 400NL PROTEIN PLUS 400NL MOTHERLIQUOR AND 100UL RESERVOIR. CONDITION WAS IDENTIFIED USING A SET OF RANDOM CONDITIONS GENERATED WITH CRYSTOOL SOFTWARE AND OPTIMIZED TO 9.576% (W/V) PEG 2000 0.2M LITHIUM SULFATE 0.1M MOPS (4-MORPHOLINEPROPANESULFONIC ACID) PH 6.5 WITH CRYSTOOL BY REDUCING THE PARAMETER SPACE TO THE REAGENTS UTILIZED. CRYSTALS SHOWED AFTER 2 DAYS
