CD33 antibodies, human

Clone: REA775 | Dilution: 1:50
Clone REA775 recognizes the human CD33 antigen, a 67 kDa glycoprotein belonging to the sialoadhesin superfamily. The CD33 antigen is highly expressed on human monocytes but weakly on granulocytes and some – but not all – myeloid dendritic cells. The CD33 antigen is also found on myeloid progenitor cells (CFU-GEMM, CFU GM, CFU-G, BFU-E) but is not expressed on lymphocytes, platelets, erythrocytes, or primitive hematopoietic stem cells.
Additional information: Clone REA775 displays negligible binding to Fc receptors.
