Abstract
Here, we describe a goniometer holder to mount standard 96-well crystallization plates directly onto the goniometer head of an oscillation camera. This attachment was designed to check crystallization conditions straight from the crystallization plates under X-rays, and was proven to be useful for checking small crystals and solutions that destabilize monoolein-based lipidic cubic phase (LCP) crystallization experiments. A quick procedure for setting up LCP assays employing commercially available instruments is also reported.
