This mixture was heated to 65?C for 3 minutes, then cooled at room temperature. After cooling, Spermidine was added to 0.5 mM. The reaction was centrifuged for 10 minutes at 13000 x g and then used in sitting-drop vapor diffusion crystallization at 4?C. 1 ?L of RNA solution was combined with 2 ?L of 10% MPD, 40 mM Na-Cacodylate pH 6.0, 12 mM Spermine, 80 mM NaCl, and 20 mM MgCl2. The well solution was 20-35% MPD. Crystals appeared and grew to full size over the course of 1-2 days.
