| 1 | VAPOR DIFFUSION, HANGING DROP | 7.2 | 290.15 | The VIM-2 in crystallization buffer (50 mM Tris/HCl pH 7.2, 100 uM ZnCl2 and 150 mM NaCl) was concentrated to 11,4 mg/mL, before 5 % Glycerol was added and the protein was flash frozen in liquid nitrogen. For crystallisation the thrawed protein solutions was mixed with precipitation solution (34% PEG3350, 0,25 M Mg formate, 5 mM BME + 2.5% of a 1M DMSO inhibitor stock in the drop) in differant ratios. As reservoir precipitation solution without inhibitor was used. |
