The monoclonal antibody 2H4 reacts with the human CC chemokine receptor, CCR7/CD197. CCR7 (previously known as BLR-2, EBI-1 and CMKBR7), a seven-transmembrane, G-protein-coupled receptor, is the specific receptor for CC chemokines, MIP-3•/Exodus 3/ELC/CCL19 and 6Ckine/Exodus 2/SLC/TCA4/CCL214. It has been shown that CCR7 mRNA is expressed mainly in lymphoid tissues including spleen, lymph nodes and tonsil. CCR7 mRNA was also detected in peripheral T- and B-lymphocytes, in BM and cord blood CD34-positive cells and mature dendritic cells. The human CCR7 gene, unlike other CC chemokine receptor genes, has been mapped to chromosome 17q12. The immunogen used to generate 2H4 hybridoma was human CCR7 transfected L1.2 mouse lymphoma cells. This antibody is not a neutralizing antibody. This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. Detection of CCR7 expression on CD4 and CD8-positive human peripheral lymphocytes by purified anti-human CCR7 antibody 2H4 (Cat. No. 550937). Human PBMC were stained with 4.0 μg/10e6 of purified 2H4 using 3-step staining protocol outlined below and anti-human CD45RA-FITC (Cat. No. 555488). The data shown are derived from the CD4- positive (based on staining with anti-human CD4-APC, Cat. No. 555349, left panel) and CD8- positive (based on staining with anti-human CD8-APC, Cat. No. 555369, right panel) lymphocyte gated populations and displayed as bivariate dot plots. Cells were analyzed with a FACScan™ Flow Cytometer
