Specifications for CD185 (CXCR5) Antibody, anti-human,


Clone REAL284 is an antibody fragment derived from the full CD185 (CXCR5) 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 REAL284 recognizes human CD185, which is a 42 kDa G-protein–coupled chemokine receptor and is also known as CXCR5, monocyte-derived receptor 15 (MDR15), or Burkitt lymphoma receptor-1 (BLR1). BLR-1 was originally identified on cells of Burkitt´s lymphoma and B cells. B cell attracting chemokine 1 (BCA-1), also known as B-lymphocyte chemoattractant (BLC) or CXCL13, is the ligand of CD185. It is further expressed on central memory CD4 T cells, T folicular helper cells, and on a migratory population of skin-derived dendritic cells.
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.
