THIS MIXTURE WAS INCUBATED OVERNIGHT AT 4C AND CENTRIFUGED TO REMOVE PRECIPITATE BEFORE SETTING UP CRYSTALLIZATION DROPS. CO-CRYSTALS WERE GROWN FROM 6 ML SITTING DROPS OF THE PROTEIN-RESERVOIR SOLUTION AND 0.3 ML OF THE RESERVOIR SOLUTION AT EITHER ROOM TEMPERATURE OR 4C, pH 6.5, VAPOR DIFFUSION, SITTING DROP, temperature 293K Resolution 2.00 Å R-free 0.259
