In summary, fluorescent microscopy is a technique that uses specialized light sources and filters to visualize fluorescent signals emitted by fluorescently-labeled specimens. Antibodies can be visualized using this technique by labeling them with a fluorescent dye or using a secondary antibody conjugated to a fluorescent molecule. The advantages of using fluorescent microscopy include the ability to specifically target and visualize a particular molecule or structure, high-resolution imaging, and both qualitative and quantitative analysis. Different types of antibodies can be visualized using this technique. However, there are limitations such as non-specific binding and the resolution and brightness of the microscope affecting sensitivity.

TL;DR Summary
Can a fluorescent tagged antibody raised against a protein be visualized under fluorescent microscope?
I'm aware that GFP tagged protein can be visualized under fluorescent microscopy. I don't know if it is possible with fluorescent tagged antibodies also. I did some research but couldn't find any information about this.

The answer provided is no.

Yes it can.
Fluorescent labeling with antibodies is a commonly used technique in many biology research labs.
Pictures.
There are a huge number of different techniques that can be used.

Similar technical principles will also apply to different labeling methods, such as labeling with biotin, enzymes or gold particles.

Related to Fluorescent Microscopy: Can Antibodies Be Visualized?

1. What is fluorescent microscopy?

Fluorescent microscopy is a type of microscopy that uses fluorescent dyes or proteins to label specific molecules or structures within a sample. These fluorescent molecules emit light when excited by a specific wavelength of light, allowing them to be visualized under a microscope.

2. How does fluorescent microscopy work?

Fluorescent microscopy works by using a light source to excite the fluorescent molecules within a sample. The excited molecules then emit light of a longer wavelength, which is captured by a camera or detector and translated into an image.

3. What are antibodies and how are they used in fluorescent microscopy?

Antibodies are proteins produced by the immune system that can bind to specific molecules or structures within a sample. In fluorescent microscopy, antibodies are labeled with fluorescent dyes and used to target and visualize specific molecules or structures of interest.

4. Can antibodies be visualized using fluorescent microscopy?

Yes, antibodies can be visualized using fluorescent microscopy by labeling them with a fluorescent dye or protein. This allows for the specific targeting and visualization of the molecules or structures that the antibodies are bound to.

5. What are the advantages of using fluorescent microscopy to visualize antibodies?

Fluorescent microscopy offers several advantages for visualizing antibodies, including high specificity and sensitivity, the ability to simultaneously visualize multiple targets, and the ability to capture dynamic processes in real-time. It also allows for the visualization of structures and molecules that may not be visible under traditional brightfield microscopy.
