Description

Clone REA340 recognizes the human CD22 antigen, a single-pass type I membrane protein which is also known as sialic acid-binding Ig-like lectin 2 (Siglec-2). In peripheral blood, cell surface expression of CD22 is found on mature B cells, but is lost during terminal differentiation to plasma cells. In bone marrow, surface expression of CD22 can be detected from the pre–B cell stage on. Cytoplasmic expression of CD22 can also be found in late pro–B cells and early–B cells. CD22 plays a strong role in cell interactions and B cell activation. It is a regulatory molecule that prevents the overactivation of the immune system and the development of autoimmune diseases. CD22 has emerged as an ideal target for monoclonal antibody based therapy of B cell malignancies including most lymphomas and many leukemias. Additional information: Clone REA340 displays negligible binding to Fc receptors.
