1VAPOR DIFFUSION, SITTING DROP295Libro 24 well sitting drop tray. Reservoir solution: 10% PEG 3350, 0.2M MgOAc Drops composed of 2ul protein + 2 ul reservoir. Frozen seed stock added to ensure nucleation. Crystals should grow overnight at 22C and fully mature within 3 days Apo crystals were soaked with inhibitor as follows: 1ul 100mM compound + 1ul well buffer Add 0.3ul to the drop Incubate at room temperature
