| 1 | VAPOR DIFFUSION, HANGING DROP | 8.3 | 281 | Crystals of human ARS2 were obtained at 4 C in 2 microliter hanging drops with a 1:1 ratio of protein solution (6 mg per ml in 20 mM HEPES, 300 mM NaCl, 2 mM tris(2-carboxyethyl)phosphine, pH 7.8) to crystallisation solution. The crystallisation solution was 0.2 M potassium citrate tribasic monohydrate, 20 % (w/v) PEG 3350. |
