Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 7.6 293 2 ul protein solution (5 mg/ml protein in 20 mM Tris, pH 7.6, 150 mM NaCl, 10 mM DTT) were mixed with 2 ul reservoir buffer consisting of 100 mM Hepes, pH 7.6, 10 mM DTT, and 14-21% (w/v) polyethylene glycol (PEG) 4000 above 500 ul reservoir buffer. Colorless plate-shaped crystals were obtained within a few days. VAPOR DIFFUSION, SITTING DROP, temperature 293K
