Used to measure catalase (CAT) enzyme activity in mouse biological samples such as tissue homogenates, blood, and cell lysates. This kit enables researchers to quantify CAT levels in studies related to oxidative stress, antioxidant defense mechanisms, and reactive oxygen species (ROS) metabolism. Commonly applied in biomedical research involving liver function, neurodegenerative diseases, aging, and inflammation. Provides a sensitive and specific method for detecting changes in CAT activity in response to drugs, toxins, or genetic modifications in mouse models.
