The Hemagglutination Inhibition Assay to Detect Serum Antibodies Against a Target Antigen

The video demonstrates a hemagglutination inhibition assay for detecting serum antibodies against specific antigens. Confirmation of hemagglutination inhibition in the test well and hemagglutination in the control well is achieved through distinct visual patterns. This assay plays a crucial role in assessing immune response, vaccine effectiveness, and studying viral infections in virology and immunology.
