Used in veterinary research and diagnostic laboratories to detect and quantify Immunoglobulin A (IgA) levels in canine biological samples such as serum, plasma, or saliva. This kit supports the assessment of mucosal immunity in dogs, aiding in studies related to gastrointestinal health, respiratory infections, and immune response to vaccines. It is also employed in monitoring immune status in breeding programs and in the investigation of autoimmune or inflammatory diseases in canine models. The assay provides a reliable, sensitive, and high-throughput method for researchers focusing on canine immunology and infectious disease progression.
