Used in biomedical research to detect and quantify STAT3 protein levels in mouse samples, this ELISA kit enables researchers to study signaling pathways involved in immune responses, inflammation, cell growth, and cancer development. It is widely applied in preclinical studies to evaluate the activation status of STAT3 in tissues or cell lysates, especially in research focused on cytokines, growth factors, and oncogenic signaling. The kit supports high-throughput analysis and provides a reliable method for assessing the effects of drugs or genetic manipulations on the JAK-STAT pathway in mouse models.
