1LIPIDIC CUBIC PHASE29330% (v/v) PEG 300, 0.1 M MES pH 6.0, 0.1 M sodium chloride, 0.1 M magnesium chloride (precipitant); Concentrated protein was mixed with molten monoolein in a 1:1.5 (w/w) ratio of protein:lipid using coupled syringes. A Mosquito LCP (TTP Labtech) robot was used to dispense a typical volume of 50-75 nL of protein/lipid mixture onto a 96-well glass sandwich plate, which was covered with 750 nL precipitant solution. Monoolein was doped with 2% CDP-DAG.
