Used in research and therapeutic development for disorders related to iron metabolism, particularly anemia of chronic disease, cancer-related anemia, and inflammatory conditions where hepcidin levels are elevated. Binds specifically to hepcidin, a key regulatory hormone of iron homeostasis, neutralizing its activity. This promotes iron release from macrophages and enhances intestinal iron absorption, increasing iron availability. Supports diagnostic assays to measure hepcidin levels and evaluate iron regulation pathways.
