| 1 | VAPOR DIFFUSION, HANGING DROP | 7.4 | 289 | 1 ul of 30 mg/ml protein in 10 mM Tris pH 7.5 and 150 mM NaCl buffer was mixed with 1 ul of the well condition (0.2 M Li2SO4, 0.1 M Tris:HCl, 2.0 M (NH4)2SO4, 5 mM ZnCl2, final pH 7.4) and equilibrated against well solution in 15 Well Crystallization Plate (Qiagen). Crystals were soaked with 100 mM ZnCl2 in 100 mM Tris, final pH 7.4, to final concentration of 100 mM |
