Immunocytochemistry is the method of visualization of proteins in cells with the use of antibody that recognize specific molecules. Recently the visualization of these antibody-bound molecules is realized with the imaging of fluorescently-labeled antibodies against these receptors. Which type of microscopy would be used for this study? 0. Confocal microscopy O. Phase-contrast microscopy O. Differential interference contrast microscopy Electron phase-contrast microscopy You are working on a project that involves an imaging of rough endoplasmic reticulum shown here. What microscope was...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
