Used in immunological research to detect and quantify duck IgM antibodies in biological samples. Commonly applied in veterinary diagnostics and avian disease studies to monitor immune responses in ducks, especially during infections such as duck hepatitis virus, avian influenza, or other poultry pathogens. Enables researchers to evaluate vaccine efficacy and immune system activation in waterfowl. Suitable for serum, plasma, or tissue homogenate samples, providing a reliable tool for monitoring health and disease progression in duck populations. Widely used in poultry research laboratories and diagnostic facilities.
