Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	5.5	294	The purified protein was concentrated to 10-20 mg/ml and buffer exchanged into 25 mM Tris-HCl, pH 8.0, 30-50 mM NaCl, 25 mM sodium citrate. DMO crystals were grown using the vapor diffusion by sitting drop method, with a reservoir solution of 8-11% PEG 6000, 100 mM sodium acetate buffer pH 5.5, 1 M LiCl, and 4 uL droplets of varying protein-to-precipitant ratios., VAPOR DIFFUSION, SITTING DROP, temperature 294K
