X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.0	293	rystals of apo-HCA II were obtained through hanging drop method. 10 ul drops of equal amounts of protein and precipitant were equilibrated against precipitant solution (1.3 M Sodium Citrate, 100mM Tris-HCl, pH 7.0) by vapor diffusion at room temperature (~20 C). A crystal was cryoprotected by quick immersion into 20% glycerol mother liquor and flash-cooled by exposing it to a gas stream of nitrogen at 100K, vapor diffusion, hanging drop, temperature 293K
