Used in immunological research to detect and quantify chicken IgG antibodies in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in studies related to poultry health, vaccine development, and immune response monitoring. Enables researchers to assess antibody levels in infectious disease models, including avian influenza, Newcastle disease, and other poultry pathogens. Suitable for high-throughput screening in laboratories focused on veterinary diagnostics and immunology. Provides a reliable and sensitive method for measuring specific immune responses in chickens, supporting both academic research and vaccine efficacy testing.
