Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.2	285	RabGGTase in 20mM Hepes pH7.2, 100mM NaCl and 2mM DTT was mixed with 15% PEG3350, 0.2M Ca Acetate, 0.1M Hepes pH7.2. The obtained crystals was soaked with 20% PEG3350, 0.2M Ca Acetate, 5% Glycerol in the presence of 1mM inhibitor for 12 hour, VAPOR DIFFUSION, HANGING DROP, temperature 285K
