Crystallization Conditions

crystal ID	method	pH	temperature	details
1	VAPOR DIFFUSION, HANGING DROP	8.1	16 *	CRYSTALS WERE GROWN USING THE HANGING DROP METHOD FROM DROPS CONTAINING 9 MG/ML PROTEIN AT PH 8.1 IN 50 MM SODIUM PHOSPHATE BUFFER, 0.3 M SODIUM CHLORIDE, 20 MM IMIDAZOLE, AND 8.5% PEG 3350. DROPS WERE EQUILIBRATED AGAINST RESERVOIRS CONTAINING 50 MM SODIUM PHOSPHATE BUFFER, 0.3 M SODIUM CHLORIDE, 20 MM IMIDAZOLE, AND 17% PEG 3350., vapor diffusion - hanging drop
