Used in immunological research to quantify levels of complement component C3 in bovine serum, plasma, or other biological samples. This kit enables researchers to assess activation of the complement system, which plays a central role in innate immunity, inflammation, and host defense in cattle. It is particularly useful in studies related to infectious diseases, immune disorders, and vaccine development. The assay supports high-throughput analysis with high specificity and sensitivity, making it ideal for monitoring immune responses in veterinary research and diagnostic laboratories.
