Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	293	2 microlitres of (AGAO 10 mg/ml, 50mM HEPES pH 7.0) plus 2 microlitres of the reservoir solution (1.1M (NH4)2SO4, 150mM Na-citrate pH 6.5) Crystals were cryoprotected and soaked with MOBA. Crystals were soaked in well solution plus 20% glycerol plus 10-fold excess of MOBA., for 48 hours. The glycerol concentration was then raised to 30% over 30 minutes, prior to flash freezing., VAPOR DIFFUSION, HANGING DROP, temperature 293K
