Used in immunological research to detect and quantify IgM antibodies in biological samples. Helps in studying immune responses, particularly during early stages of infection, due to IgM's role as the first antibody produced in an immune reaction. Widely applied in infectious disease research, including viral and bacterial infections, to assess recent or acute exposure. Also utilized in autoimmune disease studies and vaccine development to monitor IgM-specific responses. The kit enables high-throughput analysis in clinical and research laboratories using standard ELISA equipment.
