Pigment Extraction Labster Quiz Questions: Directions: Highlight the correct answer for each question. There are a number of fixation methods suitable for fluorescence microscopy that fall into two basic categories: aldehyde fixatives and alcohol fixatives. They observe how the virus infects the lymphocytes and how it inhibits inflammation. Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light.
