1 | 6.4 | 293 | Drops contained 1uL protein with 3uL reservoir solution. WT-MauG and MADH were each reduced in an anaerobic glove box prior to preparing the protein mixture for crystallization. Protein mixture: 100uM reduced WT-MauG and 50uM reduced MADH in 10mM potassium phosphate pH7.5 with 2mM sodium dithionite. Reservoir solution contained: 22% w/v PEG 8000, 0.1M sodium acetate, 0.1M MES pH 6.4 and 2mM sodium dithionite. Crystallization was carried out in an anaerobic glove box at ambient temperature., VAPOR DIFFUSION, HANGING DROP, temperature 293K |
