IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, HANGING DROP291Crystallization set-ups were made by mixing 4 uL of 350 uM RNA solution [1 mM Na 2 EDTA (pH 8.0) and 10 mM Tris-HCl (pH 8.0)] with 2 uL of a crystallization buffer composed of 3.0 M ammonium sulfate, 10 mM magnesium chloride, 10 mM manganese chloride, and 50 mM potassium 3-(N-morpholino) propanesulfonic acid (MOPS), pH 7.0 at 18 C.
