CD185 (CXCR5) antibodies, mouse

Clone: REA215 | Dilution: 1:50
Clone REA215 recognizes murine CD185, which is a 42 kDa multipass chemokine receptor, also known as CXCR5 or burkitt lymphoma receptor-1 (BLR). Expression of CD185 is found on mature recirculating B cells, a small subset of CD4
and CD8
T cells, and skin-derived migratory dendritic cells. CXCR5 recognizes B cell–attracting chemokine 1 (BCA-1)/ CXCL13 as ligand, which is a homeostatic chemokine, constitutively secreted by stromal cells in B cell areas of secondary lymphoid tissues (follicles). CXCR5 is involved in recruitment of circulating naive B cells to follicles and trafficking and homing of B1 B cells. Mice lacking CXCR5 gene display defective primary follicles and germinal centers formation in the spleen and Peyer patches, and lack inguinal lymph nodes.
Additional information: Clone REA215 displays negligible binding to Fc receptors.

In order to compare the epitope specificity of REAfinity Clone REA215 with other known clones, a competition assay was performed. 
 Cells were incubated with an excess of purified unconjugated REAfinity Antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.
