Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 6.5 293 200 nL of protein at 9.7 mg/mL in 5mM HEPES pH 7.5, 50 mM NaCl, 0.3 mM TCEP was equilibrated against 150 nL 20% MEPEG, 0.2M MgCl2, 0.1M bistris HCl pH 6.5 in a SD2 plate using a Mosquito crystallization robot. Samples were cryoprotected with reservoir solution supplemented to 35% MEPEG 2000. Samples looped in Mitegen micro mounts were flash cooled by immersion in liquid nitrogen
