Used in immunological research to quantitatively measure Rabbit Complement Protein 3 (C3) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly useful in studies related to the innate immune system, inflammation, and host defense mechanisms in rabbits. It enables researchers to assess complement system activation in disease models, including infections, autoimmune conditions, and inflammatory disorders. The assay provides high sensitivity and specificity, making it suitable for preclinical studies and veterinary research where monitoring complement activity is essential.
