1 | VAPOR DIFFUSION, HANGING DROP | 7 | 298 | SsuE was concentrated to ~10 mg/mL in 10 mM HEPES, pH 7.0. Crystals were grown at room temperature using hanging drops made with the 4 l of protein stock mixed with 2 l of a reservoir containing 7.5% (w/v) polyethylene glycol (PEG) 3350, and 0.1 M sodium citrate, VAPOR DIFFUSION, HANGING DROP, temperature 298K |
