Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8	295	Crystals were grown by mixing 1 uL of concentrated protein (10.7mg/mL) with 1 uL of mother liquor (50 mM imidazole pH 8, 0.8M sodium citrate) at room temperature, using the hanging drop vapor diffusion technique. The crystals reached usable size within 24 hours, and were then directly transferred to a cryoprotectant solution containing 50mM imidazole pH 8, 75mM NaCl, 1M sodium citrate, 10% glycerol., VAPOR DIFFUSION, HANGING DROP, temperature 295K
