Used in biomedical research to quantify Janus kinase 2 (JAK2) protein levels in cell lysates, tissue extracts, or biological fluids such as serum and plasma. Enables researchers to study JAK2 expression and activation in signaling pathways related to immune responses, inflammation, hematopoiesis, and cancer. Commonly applied in studies of myeloproliferative disorders, autoimmune diseases, and drug development targeting JAK-STAT signaling. Provides a reliable, sensitive, and high-throughput method for monitoring changes in JAK2 due to genetic mutations, cytokine stimulation, or therapeutic interventions.
