Imaging of Lipidic Cubic Phase (LCP) Plates

December 23, 2016 by Lance Ramsey Leave a Comment

Those conditions that are determined as optimal for crystallization per FRAP are subsequently used as the basis for a crystallization screen. After an extended period of time, the crystallization plates are imaged in the hopes of finding well-formed...
