Used in immunological research to quantify mouse complement protein 3 (C3) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess complement system activation in mouse models of inflammation, autoimmune diseases, infections, and neurodegenerative disorders. It is commonly applied in studies related to immune response modulation, drug development, and disease progression monitoring where the complement pathway plays a critical role. The assay provides a sensitive and specific measurement, supporting high-throughput analysis in preclinical research settings.
