| 1 | LIPIDIC CUBIC PHASE | 293 | reconstituted into lipidic cubic phase (LCP) by mixing with 9.9 MAG (Monoolein, Sigma) using a syringe mixer as described previously (Caffrey and Cherezov, 2009). 35 % (w/w) of the receptor solution was mixed with 61.5 % monoolein (w/w), additionally supplemented with 3.5 % cholesterol (w/w). Crystallization trials were performed in 96-well glass sandwich plates (Molecular Dimensions). The LCP drops were pipetted in a bolus volume of 50 nl using a gryphon robot and overlaid with 800 nl of precipitant solution per well. Diffracting quality crystals were obtained with 0.1 M MES pH 6.0, 0.2 M ammonium acetate and 40 % PEG400 | |
