1VAPOR DIFFUSION, HANGING DROP8.5296The protein sample was at a concentration of 2.1mg/mL in 25mM ethanolamine, and was prepared from chromatography fractions containing the co-eluted protein complex. For vapor diffusion crystallization, the precipitant solution was 2-6%(w/v) PEG8000 in 0.1M Tris-pH 8.5 buffer. A droplet using 2uL of protein and 2uL of precipitant solution was placed over a well containing 500 uL of precipitant solution. Crystals appeared within one week., VAPOR DIFFUSION, HANGING DROP, temperature 296K
