Fluorescent Antibody Technique

The Fluorescent Antibody Technique is a laboratory method used to detect specific pathogens or cells in a sample. It involves attaching a special dye that glows under a microscope to antibodies—proteins that naturally target and bind to particular microorganisms or cell markers. When these labeled antibodies are applied to the sample, they bind only to their target. Under a fluorescence microscope, the areas where the target is present will glow, allowing scientists or doctors to identify and locate the specific pathogen or cells quickly and accurately.
