Now available РChapter 3: Grid Screening and Evaluation 


After your grids are prepared, you are now ready for cryo-EM imaging. All cryo-EM grids need to be screened in order to decide whether resources should be committed towards data collection. The ideal grid contains a rich distribution of monodisperse particles that is supported by a thin layer of vitreous ice. In practice, a number of common issues at the sample or grid level can prevent the justification of data collection. This chapter covers best practices in the screening process, starting from a procedural overview of how grids are loaded into the TEM to assessing whether a grid is ready for data acquisition.
