BD, 555423, Purified Mouse Anti-Human CD22 HIB22

The HIB22 monoclonal antibody specifically binds to CD22. CD22 is a 130-140 kDa glycosylated type I integral membrane protein present on the surface of mature B cells. CD22 is expressed in the cytoplasm of virtually all B cells except plasma cells. CD45RO antigen on T cells and CD75 antigen on B cells have been identified as ligands for CD22. CD22 has been reported to participate in B-cell activation and also as an adhesion molecule. Although the immunobiology of this antigen has not been fully elucidated, reports indicate that ligation of CD22 induces constitutive internalization of the molecule followed by complete degradation.
This antibody is suitable for staining acetone-fixed, frozen tissue sections.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
