Used in immunological research to detect and quantify mouse IgG2b antibodies in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in studies involving immune response, vaccine development, and monoclonal antibody production. Helps researchers monitor IgG2b levels in mouse models of disease, including autoimmune disorders, infections, and cancer. The kit enables high-throughput analysis with high specificity, allowing differentiation of IgG2b from other immunoglobulin subclasses. Widely used in preclinical studies and biopharmaceutical quality control.
