Used in biomedical research to measure calcineurin (CaN) enzyme activity in mouse tissue samples, particularly in studies related to immune response, cardiac function, and neurological signaling. The ELISA kit allows for precise quantification of CaN protein levels in cell lysates or tissue homogenates, enabling researchers to investigate pathways involved in inflammation, transplant rejection, and diseases like Alzheimer's or heart hypertrophy. Commonly applied in preclinical studies using mouse models to evaluate therapeutic interventions targeting calcineurin-dependent pathways.
