Clone REA740 recognizes the IgD antigen. IgD is a monomeric antibody with two heavy chains of the δ class and two Ig light chains. It is expressed by B cells and co-expressed with IgM on the surface of mature and naive B cells. It is also produced in a secreted form that is found in very small amounts in blood serum.
Additional information: Clone REA740 displays negligible binding to Fc receptors.
