Used in biomedical research to detect and quantify calprotectin levels in rat samples, aiding in the study of inflammation, particularly in models of inflammatory bowel disease, arthritis, and other immune-mediated conditions. Enables researchers to assess neutrophil activation and monitor disease progression or response to treatment in preclinical studies. The kit provides a reliable and sensitive method for measuring calprotectin in serum, plasma, or tissue homogenates, supporting immunological and pathological research in rodent models.
