X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.5	277	200 nL of protein and 200 nL of reservoir were combined in a MRC SD2 crystallization plate by a Mosquito crystallization robot. The reservoir solution consisted of 2M ammonium sulfate and 0.1 M NaHEPES buffer, pH 7.5. The protein solution was 9.1mg/ml Nd88 PREPL, 5 mM HEPES, pH 7.5, 50 mM NaCL, 0.3 mM TCEP. Crystals were observed after one year incubation in the cold room.
