X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.5	293	drop: 1 uL 5 mg/mL RNA in 2.5 mM magnesium chloride, 10 mM HEPES-KOH pH 7.5 (heated to 65 C for 3 minutes, cooled at room temperature, 0.5 mM spermidine added, centrifuged for 10 minutes at 13000 x g) + 1 uL 50 mM sodium cacodylate pH 6.0, 150 mM NaCl, 4 mM CaCl2, 0.6 mM spermine, 36% 1,6-hexanediol. Crystals were flash-frozen in the mother liquor using liquid nitrogen for x-ray diffraction.
