Used in immunological research to detect and quantify rabbit IgA antibodies in biological samples such as serum, plasma, or mucosal secretions. This kit is particularly useful in studies related to mucosal immunity, infectious diseases, and immune response evaluation in rabbit models. It enables researchers to assess IgA levels accurately, supporting investigations in vaccine development, gut immunity, and host-pathogen interactions. The assay is commonly applied in veterinary research, preclinical studies, and immunology laboratories where sensitive and specific measurement of IgA is required.
