Used in immunological research to detect and quantify mouse surface membrane immunoglobulin A (mIgA) in biological samples. Commonly applied in studies involving mucosal immunity, gut-associated lymphoid tissue, and B-cell activation. Enables researchers to assess immune responses in mouse models, particularly in infections, autoimmune diseases, and vaccine development. The ELISA format allows for high-throughput, sensitive, and specific measurement of mIgA levels from cell cultures or tissue extracts.
