Crystal grow | Temperature: 277 K / Method: vapor diffusion, sitting drop / pH: 8.6 Details: 1.5-2.0 mM protein in 20 mM tris sulfate pH 8.0 buffer, mixed 1:1 with crystallization solution composed of 100 mM tris sulfate pH 8.6, 200 mM sodium acetate, and 30% w/v PEG 10000. After ...Details: 1.5-2.0 mM protein in 20 mM tris sulfate pH 8.0 buffer, mixed 1:1 with crystallization solution composed of 100 mM tris sulfate pH 8.6, 200 mM sodium acetate, and 30% w/v PEG 10000. After crystalization, soaked, under anaerobic conditions, in 20 mM dithionite for 10 minutes, and washed with anaerobic buffer. Reduced crystals were sealed in an air-tight bomb and pressurized at ~1500 psi O2 for up to 10 minutes. Crystals were harvested and cryocooled after a brief soak in 50% PEG 400 supersaturated with O2. |
