Used in veterinary research to quantify levels of complement protein 3 (C3) in canine serum or plasma samples. Helps assess activation of the complement system, which plays a key role in inflammation and immune response. Commonly applied in studies of immune-mediated diseases, infections, and autoimmune disorders in dogs. Enables researchers to monitor disease progression and evaluate treatment efficacy in conditions such as glomerulonephritis, sepsis, and systemic lupus erythematosus in canine models. Provides a reliable, sensitive, and high-throughput method for measuring C3 concentration in clinical and experimental settings.
