| 1 | VAPOR DIFFUSION, SITTING DROP | 8.5 | 283.15 | [Fe]-hydrogenase holoenzyme from M. paynteri was crystallized under 95%N2/5%H2 using 96-well two-drop MRC crystallization plates (sitting drop vapor diffusion method). 0.7 ul of 25-mg/ml reconstituted holoenzyme was mixed with 0.7-ul reservoir solution under yellow light and incubated under dark conditions. The crystals grew within two weeks in 30% w/v polyethylene glycol 4000, 200-mM lithium sulfate and 100-mM Tris pH 8.5 (JBScreen Wizard 3&4 HTS, Jena Bioscience). |
