VAPOR DIFFUSION, SITTING DROP
300
Protein was concentrated to 25 mg/mL in [20 mM Tris (pH8.0), 250 mM NaCl]. Crystals of Reg576 were obtained in 130 mM potassium bromide, 25% PEG 2000 monomethylether by the sitting-drop vapor-diffusion method at 18 deg. C, in drops
of 1 uL + 1 uL (protein:reservoir). Needle-shaped crystals appeared in less t
han a week. Cryo-cooling in liquid nitrogen was carried out using a cryo-protecting solution containing reservoir solution supplemented with 5% glycerol
