12 Questions
What is the primary function of a microscope?
To magnify an image and allow visualization of greater detail than the unaided eye.
Which of the following is not a type of light microscopy mentioned in the text?
Electron
What is the role of the condenser lens in a bright-field microscope?
To collect and focus light on the object to be studied.
What is the key difference between the interference microscope and the differential interference microscope (Nomarski)?
The interference microscope quantifies tissue mass, while the Nomarski microscope assesses surface properties.
What is the primary advantage of using a phase-contrast microscope?
It enables examination of unstained cells and tissues.
What is the purpose of the ocular lens (eyepiece) in a bright-field microscope?
To magnify the image 10x and project it to the viewer.
What is the key difference between polyclonal and monoclonal antibodies in immunocytochemical staining procedures?
Polyclonal antibodies are directed against different types of epitopes, while monoclonal antibodies are binding-specific.
What is the primary purpose of using a dark-field microscope clinically?
To examine autoradiographs and demonstrate specific bacteria
Which microscopy technique is best suited for visualizing the smallest resolvable distance between points?
Atomic force microscopy
What is the key difference between a direct fluorescence assay (dFA) and an indirect fluorescence assay?
A positive dFA test uses one antibody to detect an antigen, while a positive indirect test uses two antibodies to detect an antigen.
Which microscopy technique is best suited for examining autoradiographs and demonstrating specific bacteria?
Dark-field microscopy
What is the primary advantage of using monoclonal antibodies over polyclonal antibodies in immunocytochemical staining procedures?
Monoclonal antibodies are more specific to a single epitope, while polyclonal antibodies are directed against different types of epitopes.
