Used in biomedical research to detect and quantify STAT protein levels in cell or tissue samples. Helps study signaling pathways involved in immune responses, cell growth, and cancer development. Enables researchers to evaluate activation states of STAT proteins in response to cytokines or growth factors. Widely applied in immunology, oncology, and drug development studies to assess the efficacy of therapeutic agents targeting JAK-STAT pathways. Provides a reliable, high-throughput method for monitoring protein phosphorylation and expression in experimental models.
