Biology Electrophoretic Mobility Shift Assay (EMSA) for the Study of RNA-Protein Interactions: The IRE/IRP Example Carine Fillebeen1,2, Nicole Wilkinson1,2, Kostas Pantopoulos1,2 1Lady Davis Institute for Medical Research, Jewish General Hospital, 2Department of Medicine, McGill University Here we present a protocol to analyze RNA/protein interactions. The electrophoretic mobility shift assay (EMSA) is based on the differential migration of RNA/protein complexes and free RNA during native gel electrophoresis. By using a radiolabeled RNA probe, RNA/protein complexes can be visualized by autoradiography. Biology Detection of Viral RNA by Fluorescence in situ Hybridization (FISH) Kishanda Vyboh1,2, Lara Ajamian1,3, Andrew J. Mouland1,2,3 1Lady Davis Institute for Medical Research, Sir Mortimer B. Davis Jewish General Hospital, 2Department of Microbiology and Immunology, McGill University, 3Department of Medicine, Division of Experimental Medicine, McGill University A fluorescence in situ hybridization (FISH) method was developed to visually detect viral genomic RNA using fluorescence microscopy. A probe is made with specificity to the viral RNA that can then be identified using a combination of hybridization and immunofluorescence techniques. This technique offers the advantage of identifying the localization of the viral RNA or DNA at steady-state, providing information on the control of intracellular virus trafficking events.
