Reservoir solutions were prepared by a Tecan robot and 200-nL crystallization drops were dispensed on 96x3-well CrystalQuick plates (Greiner) by a Cartesian nanodrop robot (Genomic Solutions) at the joint IBMB-CSIC/IRB/Barcelona Science Park High-Throughput Crystallography Platform (PAC). Best crystals appeared after 2-3 weeks in a Bruker steady-temperature crystal farm at 20 C with 0.2 M zinc acetate dihydrate, 0.1 M sodium cacodylate, 9% PEG 8000, pH 6.5 as reservoir solution. These conditions were successfully scaled up to the microliter range with Cryschem crystallization dishes (Hampton Research) using drops containing 3 microl of protein solution (16.5 mg/ml) and 1 microl of reservoir solution, VAPOR DIFFUSION, SITTING DROP, temperature 293K |
