Crystallization Conditions

crystal ID	method	pH	temperature	details
1	VAPOR DIFFUSION	6.8	277-281 *	30 - 40 MG/ML PROTEIN SOLUTION WAS PREPARED BY DISSOLVING 4-TIME RECRYSTALLIZED CANAVALIN IN DISTILLED WATER PLUS TRACE NH4OH. RESERVOIR SOLUTION CONTAINED 2.0 % NACL IN 50 MM PHOSPHATE BUFFER AT PH 6.8. CRYSTALS WERE OBTAINED BY MIXING PROTEIN AND RESERVOIR SOLUTION IN SITTING DROPS FOLLOWED BY VAPOR DIFFUSION AGAINST THE RESERVOIR., vapor diffusion
