Method pH Temprature Details
X-RAY DIFFRACTION ? 296 Initial crystals were grown by vapor diffusion using hanging drops formed from mixing a 2:1 volume ratio of the protein complex with an equilibration buffer consisting of 22.5-25% polyethylene glycol (PEG) molecular weight 3350 Da, 300 mM Li2SO4, and 100 mM Bis-Tris pH 5.8-6.2, at 23 C. Higher quality crystals were obtained by micro-seeding and addition of 5% PEG 400 as an additive. For cryoprotection crystals where transferred directly into a buffer with a 25% PEG 3350 Da, 5-10% PEG 400 Da, 300mM Li2SO4, 100mM Bis-Tris pH 5.8-6.2, 7.5% glycerol, and flash-cooled immediately afterward to -160 C. , VAPOR DIFFUSION, HANGING DROP, temperature 296K
