Used for the quantitative measurement of catalase (CAT) enzyme activity in biological samples such as tissue homogenates, blood, and cell lysates from rabbits. This ELISA kit enables researchers to assess oxidative stress levels by measuring the amount of hydrogen peroxide decomposed by catalase, providing insights into antioxidant defense mechanisms. Commonly applied in studies related to oxidative damage, inflammation, toxicology, and disease progression in rabbit models. The assay is useful in pharmaceutical research, veterinary science, and experimental biology where accurate and sensitive detection of catalase activity is required.
