SINGLE CRYSTAL QUARTZ CHIPS FOR PROTEIN CRYSTALLIZATION AND X-RAY DIFFRACTION DATA COLLECTION AND RELATED METHODS

摘要

A crystallization device for in situ x-ray diffraction of biological samples includes a flat plate made of single crystal quartz, silicon or sapphire and having an array of wells or lanes defined on the plate. The crystallization device may be in the form of a cover slide used with a crystallization plate in a vapor diffusion setup. Also disclosed is a method for preparing biological samples for crystallization and x-ray diffraction, including: obtaining a crystallization device made of single crystal quartz, silicon or sapphire; loading a solution containing biological molecules onto the crystal support device; maintaining the solution in a crystal growth environment to grow crystals of the biological molecules; removing the crystal support device carrying the crystals from the crystal growth environment; exposing the crystals carried on the crystal support device to an X-ray beam; and recording X-ray diffracted by the biological crystals.
