This protocol can be applied to both genetic or pharmacological mouse models characterized by cognitive deficits. Biology Visualization of Endoplasmic Reticulum Subdomains in Cultured Cells Matteo Fossati1,2,3, Nica Borgese2,3,4, Sara Francesca Colombo2,3, Maura Francolini1,2 1Fondazione Filarete, 2Department of Biotechnology and Translational Medicine, University of Milan, 3Neuroscience Institute, National Research Council (CNR), 4Department of Health Science, "Magna Graecia" University of Catanzaro We describe the imaging approaches we use to investigate the distribution and mobility of the transfected fluorescent proteins resident in the endoplasmic reticulum (ER) by means of the confocal imaging of living cells. We also ultrastructurally analyze the effect of their expression on the architecture of this subcellular compartment.
