| 1 | VAPOR DIFFUSION, HANGING DROP | 10.5 | 277 | Crystals of ARS2 were obtained at 4 C in 2 microlitre hanging drops with a 1:1 ratio of protein solution (6 mg/ml in 20 mM HEPES, 300 mM NaCl, 2 mM tris(2-carboxyethyl)phosphine pH 7.8) to crystallisation solution. The crystallisation solution was 1.2 M sodium dihydrogen phosphate, 0.8 M dipotassium hydrogen phosphate, 0.2 M lithium sulphate, 0.1 M CAPS pH 10.5 |
