1 | vapor diffusion - hanging drop in anaerobic atmosphere | 7.5 | FDH-H WAS CRYSTALLIZED BY HANGING DROP VAPOR DIFFUSION IN AN ANAEROBIC ATMOSPHERE IN THE PRESENCE OF 1.5 M AMMONIUM SULFATE, 1% PEG 400, 20 MM SODIUM FORMATE AND 100 MM HEPES/NAOH AT PH 7.5. PRIOR TO FREEZING IN LIQUID NITROGEN, CRYSTALS WERE OXIDIZED BY SOAKING IN 10 MM BENZYL VIOLOGEN FOR 30 MINUTES., vapor diffusion - hanging drop in anaerobic atmosphere |
