Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 6 298 PFN1 crystals were grown by hanging drop vapor diffusion after mixing the PFN1 protein with a 1:1 ratio of reservoir solution at 298K for E117G. Reservoir solution for E117G contained 50 mM KH2PO4, 41% (wt/vol) PEG 8,000 and 100 mM MES
