Used in biomedical research to quantify ferroportin (FPN), the primary iron exporter in human cells, in cell lysates, tissue extracts, and biological fluids. Enables researchers to study iron homeostasis in conditions such as anemia, hemochromatosis, and chronic inflammation. Commonly applied in studies involving macrophages, hepatocytes, and enterocytes where iron regulation is critical. Supports drug development and evaluation of therapeutic agents targeting iron metabolism pathways. Provides a reliable, sensitive, and specific method for high-throughput screening in clinical and experimental settings.
