ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8.5	291	Hanging drops of 1 microL of 29.5 mg/mL of reduced protein and 2 microL reservoir buffer were allowed to equilibrate above the reservoir buffer (32% (w/v) polyethylene glycol 5000, 50 mM lithiumsulfate, 50 mM Tris-HCl pH 8.5). The protein solution was 17.5 mM sodium phosphate, 25 mM sodium chloride, 15 mM sodium dithionite (pH 7.6).
