Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP		293	0.2 M MgCl2, 0.1 M Tris:HCl pH 8.5, 16% (w/v) PEG 4000. Crystals formed in 1:2 ratio of protein (11.8 mg/mL) to mother liquor. 2.5 uM protein was incubated with 50 uM inhibitor for 1h at 37oC. Mixture was washed 3x with buffer in a spin concentrator and then concentrated to 11.8 mg/mL final concentration.
