1 | VAPOR DIFFUSION, SITTING DROP | 6 | 288 | A mixture solution containing 3mg/ml halorhodopsin, 1M ammonium sulfate, 0.1M NaCl, 0.1 M sodium citrate, and 5.7mg/ml nonylglucoside was concentrated by the sitting-drop vapor diffusion method. Before data collection, the crystal was soaked in an alkaline solution containing no halide ions, illuminated with red light, and then soaked in a solution at pH 7. |
