| 1 | VAPOR DIFFUSION, SITTING DROP | 291.15 | Native wild type CsaC crystallized in sitting drop setups at concentrations of 18 mg/ml. Fine screens around initial screening conditions resulted in many isomorphous crystals. Mother liquor contained 50 mM HEPES pH 7.0, 100 mM HEPES pH 7.6, 100 mM NaCl, 5 mM MgCl2, 1 mM EDTA, and 31-42% PEG200. | |
