1	VAPOR DIFFUSION, HANGING DROP	4.9	294	A 4 UL drop of protein solution [10 mg/mL protein, 50 mM bicine (pH 8.5), 100 UM MnCl2, 1 mM TCEP] was mixed with a 4 UL drop of precipitant solution [31% PEG 300, 0.1 M sodium acetate (pH 4.9)] on a siliconized cover slide and equilibrated against a 500 UL reservoir of precipitant solution at 294K. The yielded crystal is apo. To obtain the Mn2+2 bound form, this apo-crystal was soaked with 5 mM MnCl2 in 0.1 M sodium malonate (pH 8.0), 27% PEG 3350) for 24 hours, VAPOR DIFFUSION, HANGING DROP
