Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION	4.5	280	Under typical crystallization conditions the reservoir contained 80 mM ammonium sulfate and 12% (w/v) polyethylene glycol 8000. This was allowed to equilibrate with a hanging drop containing 2 microliters of the reservoir solution and 2 microliters of a 10 mg/mL protein solution in 25 mM sodium acetate (pH 4.5). , VAPOR DIFFUSION, temperature 280K
