What is immunofluorescence confocal microscopy?
Immunofluorescence (IF) microscopy is a widely used example of immunostaining and is a form of immunohistochemistry based on the use of fluorophores to visualize the location of bound antibodies.
How do you prepare a specimen for confocal microscopy?
Specimens that have three-dimensional structure that is to be studied with the confocal microscope, have to be mounted in such a way as to preserve the structure. Some sort of spacer, such as fishing line or a piece of coverslip, is commonly placed between the slide and the coverslip to avoid deforming the specimen.
What type of microscope is used for immunofluorescence?
Several microscope designs can be used for analysis of immunofluorescence samples; the simplest is the epifluorescence microscope, and the confocal microscope is also widely used. Various super-resolution microscope designs that are capable of much higher resolution can also be used.
What is the advantage of a confocal microscopy over fluorescence microscope?
Confocal microscopy offers several distinct advantages over traditional widefield fluorescence microscopy, including the ability to control depth of field, elimination or reduction of background information away from the focal plane (that leads to image degradation), and the capability to collect serial optical …
What is confocal fluorescence microscopy used for?
Confocal fluorescence microscopy is a commonly used optical imaging method in biology, combining fluorescence imaging with confocal microscopy for increased optical resolution.
Is fluorescence microscopy a light microscope?
What Is Fluorescent Microscopy? A fluorescence microscope is much the same as a conventional light microscope with added features to enhance its capabilities. The conventional microscope uses visible light (400-700 nanometers) to illuminate and produce a magnified image of a sample.
How does confocal microscopy work in fluorescence microscopy?
In fluorescence microscopy, any dye molecules in the field of view will be stimulated, including those in out-of-focus planes. Confocal microscopy provides a means of rejecting the out-of-focus light from the detector such that it does not contribute blur to the images being collected.
How to prepare cells for immunofluorescence fixation?
Transfer your cells into the plates and culture them (eg overnight) so they are well adhered and so they are 40-70% confluent when they are ready for fixation. Do what ever you want to the cells – transfect them, stimulate them, inhibit them, inhibit them then stimulate them.
How is indirect immunofluorescence used in brain staining?
Indirect immunofluorescence is a technique that enables the visualization of specific targets using a combination of primary and secondary antibodies. This protocol details a procedure for staining frozen brain floating cryosections greater than 30 micrometers in thickness. available in your country.
Can a lmcf microscope image a range of fluorophores?
Most of the LMCF microscopes are quite versatile and can image a range of fluorophores. Here are some typical fluorophores to use (you can use the fluophore spectra links on the reference page and the information on the relevant microscope page to work out other combinations)
