Used in immunological and biomedical research to detect and quantify STAT6 protein levels in cell lysates or tissue samples. Helps study the activation of the JAK-STAT signaling pathway, particularly in response to interleukins such as IL-4 and IL-13. Commonly applied in research on allergic responses, asthma, immune regulation, and cancer. Enables researchers to assess phosphorylation and expression levels of STAT6, providing insight into cellular signaling mechanisms and potential therapeutic targets. Widely used in preclinical studies and drug development involving immune system modulation.
