X-RAY DIFFRACTION

Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 8.5 291 HMGR at 10 mg/ml was supplemented with a final concentration of 2 mM NADPH. The sample was centrifuged for 5 minute at 13.000 RPM to remove any aggregates and dust. 0.7 ul of protein sample was spotted on a 96-well 2-drop MRC Crystallization Plates (Molecular Dimensions, Suffolk, UK) and 0.7 ul of reservoir solution was mixed. The best crystals were obtained after several month using a solution containing 40% v/v PEG 400, 100 mM Tris PH 8.5 and 200 mM Li2SO4.
