Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	8.6	277	1.5-2.0 mM protein in 20 mM tris sulfate pH 8.0 buffer, mixed 1:1 with crystallization solution composed of 100 mM tris sulfate pH 8.6, 200 mM sodium acetate, and 30% w/v PEG 10000, to yield a final volume of 150-200uL; this was equilibrated against 30mL of same crystalization solution.
