X-RAY DIFFRACTION 7.0 293 Initial crystallization experiments were carried out by sitting-drop vapor diffusion in a 96-well format, using a Phoenix liquid-handling robot with a panel of commercial sparse-matrix screens (PEG/Ion 1 and 2 from Hampton Research, Wizard 2 from Emerald Biosciences, JCSG Plus Suite from Qiagen, and JBScreen 6 from Jena BioScience). Quality diffracting crystals of L1/M12B9-Fab complex were obtained at RT by mixing 0.5ul of protein solution at 9.5 mg/ml with 0.5ul of precipitant [100 mM Tris, pH 7.0, 20% (w/v) polyethylene glycol (PEG) 3000, and 200 mM Ca(OAc)] and seeding with initial crystals obtained at 6.5 mg/ml. Crystal were flash-frozen at 100K in mother liquor containing 20 % glycerol.
