Antibody Techniques, Fluorescent

Test for Tissue Antigen using either a direct method, by conjugation of antibody with fluorescent dye (Fluorescent Antibody Technique, Direct) or an indirect method, by formation of Antigen-Antibody Complex which is then labeled with Fluorescein-conjugated anti-Immunoglobulin antibody (Fluorescent Antibody Technique, Indirect). The Tissue is then examined by Fluorescence Microscopy.
