Crystals were grown on an XtalTool support (Jena Bioscience) over a 24 well VDX-plate with 1 ml reservoir. The drop consisted of 1 microlitre 20 mg/ml protein in 10 mM sodium phosphate pH 7.4, 100 mM NaCl, 10 mM beta-mercaptoethanol, 2 mM lactose), 0.25 microlitre of seed crystals in a stabilization solution containing 0.1 M Tris pH 7.5, 33% (w/v) PEG 4000, 0.1 M MgCl2, 0.2 M NaSCN) and 0.75 microlitre reservoir solution containing 0.1 M Tris pH 7.5, 30% PEG 4000, 0.05 M MgCl2, 0.2 M NaSCN and 8 mM beta-mercaptoethanol. |
