ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8.5	291	Hanging drops of 1 microL of 30.1 mg/mL of reduced protein and 1 microL reservoir buffer were allowed to equilibrate above the reservoir buffer (30% (w/v) polyethylene glycol 5000, 60 mM lithiumsulfate, 50 mM Tris-HCl pH 8.5). The protein solution was 26 mM sodium phosphate, 37 mM sodium chloride, 14 mM sodium dithionite (pH 7.6).
