X-RAY DIFFRACTION	?	277	Directly after size exclusion chromatography DRH-1deltaN_E431Q was concentrated 10 mg/ml and mixed with 12 dsRNAp in a 1:2 molar ratio, ADP-AlF4 (adenosine-5-diphosphate with aluminium fluoride) and 2 mM MgCl2 were added then incubated for 30 minutes on ice. The complex was mixed with reservoir buffer (0.2 M tri Ammonium citrate 20 % PEG3350 or 0.2 M Sodium malonate dibasic monohydrate 20% PEG3350) in 1:1 ratio. Crystals grew in two weeks at 4 C.
