1	VAPOR DIFFUSION, SITTING DROP		277	BeF3- GSA complexes were obtained under vapour diffusion sitting drop conditions. Protein buffer (HRas pY64 or HRas 0.4 mM, Na-HEPES 20 mM pH = 8.0, MgCl2 5 mM, NaF 20 mM) were mixed with precipitant in a 1:1 ratio with a total drop size of 600 nL. The precipitant solution consited of: (30 % (v/v) MPD, 100 mM imidazole, pH = 7.0). Protein crystals were soaked in their respective precipitant solutions containing 50 mM BeCl2 and subsequently flash-frozen using 20% glycerol as cryoprotectant.
