A mixture of ChVLig (230 microM), nicked duplex DNA (220 microM) and 2 mM EDTA was added to an equal volume of a well solution containing 100 mM Bis-Tris-HCl (pH 6.5), 30 mM ammonium acetate, 22% PEG-4000. Crystals were grown at 22 C by the sitting-drop vapor diffusion method. Crystals appeared after 3 days. Crystals of ChVLig in complex with nicked DNA were transferred to a solution containing 100 mM Bis-Tris-HCl (pH 6.5), 110 mM ammonium acetate, 22.5% PEG-4000, 5 mM MnCl2 for 5 min, then placed into a solution containing the same components plus 15% glycerol prior to flash-freezing the crystals in liquid nitrogen., VAPOR DIFFUSION, SITTING DROP, temperature 295K |
