Definition of immunofluorescence in US English:



  • A technique for determining the location of an antigen (or antibody) in tissues by reaction with an antibody (or antigen) labeled with a fluorescent dye.

    • ‘Spindles were detected by the indirect immunofluorescence method using antitubulin antibody.’
    • ‘This is consistent with the uniformly distributed receptors found with immunofluorescence labeling.’
    • ‘Paired sera were tested using immunofluorescence or enzyme immunoassay methods to establish the serologic diagnosis.’
    • ‘Cells were therefore processed for immunofluorescence staining with anti-tubulin antibodies in order to visualize spindle morphology.’
    • ‘The resulting immunofluorescence images indicated antibody binding to the membrane through an increase in the intensity of the vesicle border upon the addition of the labeled antibody.’
