1 | VAPOR DIFFUSION, HANGING DROP | 4 | 277 | 35 microM of FluB polymerase was mixed with 40 microM of the vRNA promoter and 40 microM 13-mer capped RNA primer in a buffer containing 500 mM NaCl, 50 mM HEPES pH 7.5, 5% glycerol and 2 mM TCEP. The best diffracting crystals appeared in 100 mM sodium acetate pH 3.8 - 4.0 and 150 mM di-ammonium phosphate |
