Used in immunological research to detect and quantify MHC class II molecules in pig samples, this ELISA kit supports studies on antigen presentation and immune response regulation. It is widely applied in veterinary research, vaccine development, and transplantation immunology to assess immune activation and monitor disease progression in swine models. The assay helps evaluate the expression levels of SLA class II proteins in response to infections, making it valuable in infectious disease research such as swine flu, PRRS, and other viral or bacterial challenges. It is also used in breeding programs to study genetic diversity in immune-related genes.
