Used in immunological research to detect and quantify levels of Major Histocompatibility Complex (MHC) class I and II molecules in chicken samples. This kit supports studies in avian disease resistance, vaccine development, and immune response monitoring. It is particularly valuable in poultry health research, helping scientists assess antigen presentation and immune activation in infectious diseases such as avian influenza, Newcastle disease, and Marek’s disease. The assay enables high-throughput analysis in breeding programs focused on enhancing genetic resistance to pathogens in commercial and experimental chicken lines.
