1VAPOR DIFFUSION, HANGING DROP7.5298Drops were prepared by mixing 7 uL of the final concentrated protein (~10 mg/mL) and 3uL of precipitant solution against 1 mL of precipitant solution. The precipitant solution conditions varied, and consisted of 50 mM Tris-HCl (pH 7.5) and 1.6 M sodium citrate, VAPOR DIFFUSION, HANGING DROP, temperature 298K
