Anti-CD89 Antibody

CD89, also known as FcαRI, is a transmembrane glycoprotein that acts as the receptor for the Fc region of IgA antibodies and is expressed on neutrophils, monocytes, eosinophils, and certain macrophage populations. This unconjugated rabbit polyclonal reagent from Antibodies.com was raised against the human CD89 antigen and is supplied as 100 µl of antibody. It is validated for Western blot and ELISA workflows, making it useful for laboratories investigating IgA receptor biology, mucosal immunity, and the role of FcαRI in myeloid cell activation. The polyclonal format allows the reagent to recognize multiple epitopes on the target, supporting detection of native CD89 in human samples for research use only.
