CD141 (BDCA-3) antibodies, human

Clone: REA674 | Dilution: 1:11
Clone REA674 recognizes the human CD141 (BDCA-3) antigen, which is expressed at high levels on a minor subpopulation of human myeloid dendritic cells (about 0.02% of blood leukocytes). CD141 (BDCA-3)

myeloid dendritic cells have been designated type-2 myeloid dendritic cells (MDC2s). CD141 is also known as thrombomodulin; thrombomodulin mediates co-agglutination by interaction with thrombin and protein C, though nothing is known about its function on MDC2s.
Additional information: Clone REA674 displays negligible binding to Fc receptors.
