Used in immunological research to detect and quantify secretory immunoglobulin A (sIgA) in mouse samples such as saliva, mucosal secretions, and intestinal lavage fluids. This ELISA kit enables researchers to assess mucosal immune responses in studies related to infectious diseases, vaccine development, gut immunity, and inflammatory conditions. It is particularly valuable in preclinical studies involving mouse models of infection, allergy, or autoimmune disorders where monitoring sIgA levels helps evaluate immune activation or tolerance at mucosal surfaces. The assay provides high sensitivity and specificity, allowing for reliable measurement of sIgA concentrations in small sample volumes, supporting high-throughput screening in biomedical research.
