1	VAPOR DIFFUSION, HANGING DROP	8.5	293.15	A protein solution [11 mg/mL in 10 mM BTP buffer (pH 7.3)] was mixed 1:1 (v/v) with a reservoir solution containing 0.2 M trimethylamine N-oxide, 0.1 M Tris (pH 8.5), 15% 20% (w/v) PEG 2000 mme, 0.4 mM MnSO4. The drop sizes were 2 uL, and the volume of the reservoir solution was 500 uL, VAPOR DIFFUSION, HANGING DROP, temperature 293.15K
