1 | VAPOR DIFFUSION, SITTING DROP | 293 | 200 nL of protein at 9.8 mg/mL (0.41 millimolar) in 5mM HEPES pH 7.5, 50 mM NaCl, 0.3 mM TCEP and 0.5 millimolar resveratrol was equilibrated against 250 nL 18% PEG4000, 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 with 35% PEG4000. Samples looped in Mitegen micro mounts were flash cooled by immersion in liquid nitrogen. Crystals were grown at 293K |
