immunofluorescence

Immunofluorescence is a laboratory technique used to visualize specific proteins or antigens in cells or tissue samples. It works by attaching a fluorescent dye to antibodies that bind to these proteins. When illuminated with a special light, the dyed antibodies emit a glow, making the targeted proteins visible under a fluorescence microscope. This method helps scientists and medical professionals study the distribution and localization of proteins, aiding in research and diagnosis of diseases like cancer or autoimmune disorders by revealing how cells behave in different conditions.
