Detection of Mouse CXCR7/RDC‑1 by Western Blot. Western blot shows lysates of mouse spleen tissue. PVDF Membrane was probed with 1 µg/mL of Mouse CXCR7/RDC‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4227) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for CXCR7/RDC‑1 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of CXCR7/RDC‑1 in Mouse Neural Progenitor Cells by Flow Cytometry. Undifferentiated mouse neural progenitor cells were stained with Sheep Anti-Mouse CXCR7/RDC‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4227, filled histogram) or control antibody (Catalog # 5‑001‑A, open histogram), followed by NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010).

CXCR7 (CXC chemokine receptor 7; also GPRN1, RDC1 and chemokine orphan receptor 1) is a 60 kDa member of the G-protein coupled receptor 1 family. It is expressed on multiple cell types, including neurons, T cells, NK cells, neutrophils, B cells plus angiogenic endothelial cells. CXCR7 forms both homodimers and heterodimers with CXCR4. It selectively binds I-TAC and SDF1, and appears to involve beta -arrestin2 during signaling. Notably, a CXCR7:CXCR4 heterodimer shows increased responsiveness to SDF1, and I-TAC may actually block some SDF1-mediated migration activity. Mouse CXCR7 is a 7-transmembrane glycoprotein that is 362 amino acids (aa) in length. It contains a 47 aa N-terminal extracellular region plus a 43 aa C-terminal cytoplasmic domain. Over aa 1‑47, 103‑118, 184‑213 and 274‑296 collectively, mouse CXCR7 shares 97% and 91% aa identity with rat and human CXCR7, respectively.
