Detection of CXCR7/RDC-1 in HEK293 Human Cell Line Transfected with Human CXCR7/RDC-1 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with (A) human CXCR7/RDC-1 or (B) irrelevant transfectants and eGFP was stained with Mouse Anti-Human CXCR7/RDC-1 Monoclonal Antibody (Catalog # MAB42273R) followed by APC-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). Quadrant markers were set based on control antibody staining (Catalog # MAB002). View our protocol for Staining Membrane-associated Proteins.

CXCR7/RDC‑1 in Human Squamous Cell Carcinoma. CXCR7/RDC-1 was detected in immersion fixed paraffin-embedded sections of human squamous cell carcinoma using Mouse Anti-Human CXCR7/RDC-1 Monoclonal Antibody (Catalog # MAB42273R) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell surfaces and cytoplasm.

Background: CXCR7/RDC-1

The G protein-coupled receptor, RDC1, belongs to a subgroup of chemokine receptors and has been designated CXCR7. CXCR7 can bind with high-affinity to CXCL12/SDF-1 and CXCL11/I‑TAC. It is also a co-receptor for several HIV and SIV strains. In their N-termini and extracellular loops 1, 2, and 3, human and mouse CXCR7 share 84%, 100%, 96%, and 86% amino acid sequence identity, respectively. Reports of mRNA levels and/or protein expression (as assessed using anti-CXCR7, clone 9C4) (J. Biol. Chem. 2005, 280(42):35760, J. Immunol. 2006, 176(4):2197) indicate that CXCR7 occurs on a wide variety of tissues and cells including monocytes, B cells, T cells and mature dendritic cells. In contrast, based on ligand binding analysis and receptor level (as assessed using anti-CXCR7, clone 11G8), surface expression of CXCR7 was reported to be restricted to tumor cells, activated endothelial cells, fetal liver cells, and few other cell types (J. Exp. Med. 2006, 203(9):2201). The basis of these inconsistent observations is not known but may be attributed to cell context and the use of different antibodies that may recognize different epitopes.
