X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6.5	298	CLR/RAMP1 complex was mixed with Olcegepant prior to crystallization in a 1:4 (protein:compound) molar ratio. Crystals were obtained by mixing 0.6uL protein with 0.3uL reservoir solution containing 1-1.3M ammonium sulfate, 6-8% dioxane, 60-80mM MES pH 6.5, 0.4 M potassium thiocyanate. The crystals were transferred to 2.1M NaMalonate (pH 7.0) prior to freezing in liquid nitrogen, hanging drop, temperature 298K
