1VAPOR DIFFUSION, HANGING DROP7.5298crystals of unliganded DCS were gradually transferred to a stabilizing solution containing 100 mM Tris (pH 7.5), 200 mM Li2SO4, 17-19% PEG 4000, 2 mM 2F-FPP and allowed to soak for 16 hours. Crystals were slowly cryoprotected with stabilizing solution containing 2 mM MnCl2 and 25% glycerol and then flash cooled with liquid nitrogen., VAPOR DIFFUSION, HANGING DROP, temperature 298K
