Extra Details:: 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 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 (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. 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. Applications: Suitable for use in Flow Cytometry and Immunohistochemistry. Other applications have not been tested. Recommended Dilutions: Flow Cytometry: 0.25ug labels 10e6 cells in the MCF-7 human breast cancer cell line. Immunohistochemistry (Paraffin): 8-25ug/ml. Detected CXCR7 in perfusion fixed paraffin sections of nude mice injected with human breast cancer cells. Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
