Used in biomedical research to detect and quantify STAT6 protein levels in cell lysates, tissue extracts, and biological fluids. Enables researchers to study STAT6 activation in immune responses, particularly in IL-4 and IL-13 signaling pathways. Widely applied in immunology and cancer research to investigate Th2-mediated inflammation, allergic diseases, and macrophage polarization. Supports drug development by monitoring STAT6 expression and phosphorylation in response to therapeutic compounds. Provides a reliable, high-throughput method for assessing pathway activity in experimental models.
