Used for measuring peroxidase (POD) enzyme activity in rat biological samples such as serum, plasma, or tissue homogenates. Commonly applied in research settings to assess oxidative stress, inflammation, and antioxidant status in experimental models. The kit enables quantitative detection through a colorimetric assay, allowing high-throughput analysis in microplate format. Widely used in pharmacological, toxicological, and biomedical studies where monitoring enzyme activity helps evaluate cellular damage or the effectiveness of therapeutic interventions.
