Question

What method can be used to label microtubules with a fluorescent dye?

1) Immunofluorescence
2) Electron microscopy
3) Western blotting
4) Polymerase chain reaction

Answer 1

Immunofluorescence is a method that can be used to label microtubules with a fluorescent dye. Antibodies specific to microtubules are linked to fluorophores, which bind to the microtubules and emit visible light when exposed to UV light.

Step-by-step explanation:

Fluorescence microscopy is a technique that can be used to label microtubules with a fluorescent dye. One method is immunofluorescence, where antibodies specific to microtubules are linked to fluorophores. When added to dividing cells, the fluorophores bind to the microtubules and emit visible light when exposed to UV light. This allows for the visualization of microtubules under a fluorescence microscope.
