Used in biomedical research to measure calcineurin (CaN) enzyme activity in mouse samples, particularly in studies related to immune response, neuronal signaling, and cardiac function. The ELISA kit allows for quantitative analysis of CaN activity in tissue homogenates or cell lysates, helping researchers assess changes in enzyme function under disease conditions or after drug treatment. Commonly applied in studies of inflammation, transplant rejection, neurodegenerative diseases, and heart hypertrophy.
