Used in biomedical research to measure levels of c-Jun amino-terminal kinase (JNK) protein activity in mouse samples. This kit enables researchers to quantify phosphorylated or total JNK in cell lysates, tissue extracts, or serum, supporting studies in signal transduction, inflammation, stress response, and apoptosis. It is particularly valuable in neuroscience, immunology, and cancer research where JNK pathway activation plays a key regulatory role. The ELISA format allows for high-throughput, sensitive, and specific detection, making it ideal for preclinical studies and drug development targeting JNK-related pathways.
