X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.0	293	Directly after size exclusion chromatography chMDA5 delta CARD-Q was mixed with 10 bp dsRNA in a 1:1 molar ratio and incubated for 30 minutes on ice. The complex was concentrated to around 10 mg/ml and 2 mM AMPPNP (adenosine 5 prime -(beta,gamma-imido)triphosphate lithium salt hydrate ) was added. Sample and reservoir buffer (0.025 M Bis-Tris pH 6.5, 0.075 M succinic acid pH 7.0, 12-14 % PEG 3350, 2 % sucrose) were mixed in a 2:1 ratio. Three hours after setup, cover glasses with drops were transferred from a reservoir containing 12-14 % PEG 3350 to one containing 8 % PEG 3350. Crystals grew in one week at 20 C and were harvested in cryo-protectant solution (0.025 M Bis-Tris pH 6.5, 0.075 M succinic acid pH 7.0, 25% 3350, 10% ethylene glycol) before flash freezing with liquid nitrogen.
