| 1 | VAPOR DIFFUSION, HANGING DROP | 5 | 298 | Crystals of RNase A were grown by hanging-drop vapor diffusion technique at 298 K mixing a protein solution containing 20 mg mL-1 of RNase A with equal volumes of reservoir solution. Well diffracting crystals appeared within 15days from the following conditions:20% PEG4000 and 20 mM sodium citrate buffer pH 5.0. , VAPOR DIFFUSION, HANGING DROP |
