Used in immunological research to quantify Rat Complement Protein 2 (C2) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study the activation and regulation of the classical complement pathway in rat models, particularly in inflammation, autoimmune diseases, and immune complex-mediated conditions. It is a valuable tool for preclinical studies investigating immune responses, host defense mechanisms, and therapeutic interventions targeting the complement system. The assay provides high sensitivity and specificity, allowing accurate measurement of C2 protein concentrations to support mechanistic insights and biomarker discovery in rodent-based experiments.
