X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	8.5	298	Triclinic crystals of apo GRP78 were observed in 0.1 M Tris-HCl, 25% PEG3350, 0.1 M sodium/potassium tartrate. Initial crystals were then microseeded in 25% PEG3350, 0.1 M Tris-HCl, 0.2 M sodium chloride. These new apo monoclinic crystals were soaked with 5 mM 8-bromoadenosine for one week.
