Method Name
Immunofluorescence Assay (IFA)
Method Description
The presence of IgM-class antibody to measles is determined by an indirect immunofluorescence assay. After removal of IgG by specific immunoglobulin antibody, the serum is incubated with measles antigen, which is adhered to a glass microscope slide. Antibodies, if present, will bind to the antigen forming stable antigen-antibody complexes. If no antibodies are present, the complexes will not be formed, and the serum components will be washed away. Fluorescein-labeled antihuman-IgM antibody is added to the reaction side and binds to IgM antibodies if present. This results in a positive reaction of bright apple-green fluorescence when viewed with a fluorescence microscope.(Package insert: Measles Virus Antigen Substrate Slide. AESKU.BION; 09/2019)
