Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6	278	The C2 crystal of halorhodopsin grew when a solution containing 3 mg/ml halorhodopsin, 0.4 % nonylglucoside, 1 M ammonium sulfate, 0.16 M sodium chloride, 0.04 M sodium citrate at pH 6 and 0.04 % sodium azide was concentrated by the vapor diffusion using a reservoir solution containing 2.8 M ammonium sulfate and 0.12 M sodium citrate at pH 6. For investigation of light-induced structural changes, the C2 crystal was soaked in a solution containing 0.1 M sodium bromide, 1.5 M trisodium citrate at pH 7 and 30 % trehalose. This crystal was illuminated at 240 K with orange light and cooled to 100 K at a rate of 2.3 K/sec in the dark., VAPOR DIFFUSION, SITTING DROP, temperature 278K
