The monoclonal antibody 150503 specifically binds to the human CC chemokine receptor, CCR7, also known as CD197. CCR7 (previously known as BLR2, EBI1 and CMKBR7), a seven-transmembrane, G-protein-coupled receptor, is the specific receptor for CC chemokines, MIP-3β/Exodus 3/ELC/ CCL19 and 6Ckine/Exodus 2/SLC/TCA4/CCL21. CCR7 mRNA is expressed mainly in lymphoid tissues including the spleen, lymph nodes and tonsil. CD197/CCR7 is expressed on peripheral T and B lymphocytes by bone marrow and cord blood CD34-positive cells and by mature dendritic cells. In response to its cognate chemokines, CD197/CCR7 mediates homing of leucocytes to secondary lymphoid tissues. Differential CCR7 expression can be used to distinguish naive, central memory, and effector memory T cell subsets. The human CCR7 gene, unlike other CC chemokine receptor genes, has been mapped to chromosome 17 (region 17q12).
Caution: Under some complex multi-color conditions, this clone may non-specifically interact with antibodies conjugated with APC-H7 or APC-Cy7, contributing to staining artifacts. BD Horizon Brilliant™ Stain Buffer (Cat. No. 563794), designed to minimize on non-specific fluorescent dye interactions, does not resolve this interaction with either APC-H7 or APC-Cy7. For optimal multicolor staining results, alternatives to APC-H7 and APC-Cy7 should be evaluated.
