Clone REAL222 is an antibody fragment derived from the full CD304 (BDCA-4) antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity.
Clone REAL222 recognizes the human CD304 (BDCA-4) antigen. Like CD303 (BDCA-2), the CD304 (BDCA-4) antigen is specifically expressed on human plasmacytoid dendritic cells in blood and bone marrow. Unlike CD303 (BDCA-2), expression of CD304 (BDCA-4) is up-regulated on plasmacytoid dendritic cells and induced on myeloid cells upon culturing. In inflamed tonsils, CD304 expression, apart from plasmacytoid dendritic cells, is also detected primarily on follicular B helper memory T cells. The CD304 (BDCA-4) is identical to neuropilin-1 (NP-1), a neuronal receptor, which is known to be expressed on numerous nonhematopoietic cell types, including neurons, endothelial, and tumor cells. CD1a+ dendritic cells generated ex vivo from monocytes or hematopoietic precursor cells are CD304+ but CD303 (BDCA-2).
The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.
