1VAPOR DIFFUSION, SITTING DROP298The initial protein concentration was 28 mg/ml (10mM L-Malic acid, MES, Tris pH 7). Different crystal forms were obtained under crystallization conditions varying - PEG 4K, isopropanol and 10mM Hepes pH 7-7.8 with protein concentration 19-28 mg/ml. Most of the crystals that appeared within 2 weeks had visual grow defects. In one of the drops the stack of thin plates appeared after 1 month and one complete dataset was collected.
