Flow cytometric analysis of CCR7 (CD197) expression on CD4 and CD8-positive human peripheral lymphocytes. Human PBMC were stained with 0.25 µg/test of Purified Rat Anti-Human CCR7 (CD197) (Cat. No. 552175) using 3-step staining protocol outlined below and FITC Mouse Anti-Human CD45RA (Cat. No. 555488). 3-step staining was carried out with Biotin Mouse Anti-Rat IgG2a (Cat. No. 553894) and PE Streptavidin (Cat. No. 554061).  Bivariate dot plots are derived from the CD4-postive (based on staining with APC Mouse Anti-Human CD4, Cat. No. 555349, left panel) and CD8-positive (based on staining with APC Mouse Anti-Human CD8, Cat. No. 552174, right panel) lymphocyte gated populations.

Recommended Assay Procedures

Chemokine receptors are know to internalize during manipulation resulting in low frequency expression. Immunophenotyping studies of chemokine receptors need to be performed on freshly collected whole blood (<24 Hrs). Incubation with the antibody should be done in the dark. Cellular manipulation, such as Ficoll separation, freezing, or exposure to cold temperatures prior to staining have been shown to cause a decrease in staining intensity and inconsistent results.

The purified 3D12 antibody can be used for the immunofluorescent staining and flow cytometric analyses of human leukocytes and cell lines that express CCR7 (see Figure). A multiple-step staining procedure is strongly recommended to amplify immunofluorescent signals for the flow cytometric analysis of human CCR7 expression:

1. Incubate 10e6 cells with 0.1 - 0.5 µg of Purified Rat Anti-Human CCR7 (CD197) at 4°C for 15 - 20 minutes. Wash cells two times with staining medium containing sodium azide (e.g., Dulbecco's PBS or tissue culture medium [without phenol red and biotin] with 0.09% sodium azide and 2% heat-inactivated FCS or 0.2% BSA).

2. Incubate the cells with 0.25 µg of Biotin Mouse Anti-Rat IgG2a (Cat. No. 553894) at 4°C for 20 minutes. Wash cells two times.

3. Incubate the cells with ≤ 0.06 µg of streptavidin-phycoerythrin (Cat. No. 554061) at 4°C for 20 minutes. Wash two times. Resuspend cells instaining medium and analyze stained cells with a FACScan™ Flow Cytometer (BDIS, San Jose, CA) using appropriate specificity and compensation controls.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

3D12

The monoclonal antibody 3D12 reacts with the human CC chemokine receptor, CCR7. 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-3β/Exodus 3/ELC/ CCL19 and 6Ckine/Exodus 2/SLC/TCA4/CCL21. 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 bone marrow 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 3D12 hybridoma was the N-terminus as well as parts of the second extracellular loop of human CCR7 protein. The monoclonal antibody 3D12 recognizes an epitope mapping to the N-terminus of human CCR7.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
