1 | EVAPORATION | 292 | Crystals were grown by the sitting-drop vapor diffusion method. Crystals were grown at 20C by mixing 1microL of PBP5fm (48 mg/ml), 2microL of reservoir (20% PEG8000 (w/v), 0.4 M Li2SO4 and 100 mM Na acetate at pH 4.5) and 0.5 microL of 0.1M ceftobiprole (kind gift of Basilea Pharmaceutica. The crystal was cryoprotected in the same buffer containing 20 % (v/v) glycerol. Crystals were soaked for 5 min in 1 microl of 0.1 M ceftobiprole before cryoprotection. |
