X-RAY DIFFRACTION	?	277	Protein buffer (phospho-HRas pY64 0.4 mM, RasGAP 0.4 mM, Na-HEPES 20 mM pH = 8.0, MgCl2 5 mM, NaF 20 mM) was mixed with precipitant in a 1:1 ratio with a total drop size of 600 nL. The precipitant solution consits of: 100 mM NaOAc, pH = 4.5, 200 mM Li2SO4, 50% PEG400 (v/v). Protein crystals were soaked in precipitant solutions containing 50-100 mM BeCl2 and subsequently flash-frozen using 20% glycerol as cryoprotectant.
