X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	?	294	0.1-0.2 mM RNA in 10 mM Na Cacodylate pH 7, 50 mM NaCl, 10 mM MgCl2, 2.5 mM MnCl2. Crystallized in about 2 months with a mother liquor of 40 mM Na cacodylate pH 6, 15% MPD, 80 mM SrCl2, 12 mM spermine tetra-HCl at 21 C. Crystals were cryo-protected by addition of 20% PEG-400 directly before freezing.
