CXCR4 Antibody (PA3-305) in Flow

Flow cytometry analysis of CXCR4 on Ramos cells. Cells were fixed, permeabilized, and then blocked with a 1:100 dilution of normal goat serum for at least 30 minutes on ice. Cells were stained with CXCR4 polyclonal antiserum (Product # PA3-305, red histogram) or with normal rabbit serum (blue histogram) at a dilution of 1:500. After incubation of the primary antibody for at least 1 hour on ice, the cells were stained with a DyLight 488-conjugated goat anti-rabbit IgG secondary antibody (Product # 35552) for at least 30 minutes on ice.

Product Specific Information

Several different molecular weight isoforms of CXCR4 have been described in the literature, which vary depending on cell type tested and extraction buffer used. Using Ramos, Raji, and Jurkat membrane fractions, two different MW forms of CXCR4 were detected with PA3-305 by Western blot, between 55-72kD.

It is recommended to use a membrane isolation buffer/kit for extracting CXCR4 for Western blot analysis. Cellular membrane fractions were isolated for Western blot using Mem-PER Plus (Product # 89842).

Target Information

CXCR4 (Fusin, LESTR, HUMSTR) is a member of the G-protein-coupled chemokine receptor family with seven membrane-spanning domains, and functions as a co-receptor for X4 HIV-1 entry into CD4+ cells. CXCR4 has been proved to be the co-receptor for HIV-2's binding to CD4 through envelope glycoprotein gp 120 and promotes Env-mediated fusion of the virus. In other cases, CXCR4 can even function as the only receptor for HIV-2's binding to the CD4 host cells. CXCR4 is the receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. CXCR4 acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Also, CXCR4 is involved in hematopoiesis and in cardiac ventricular septum formation, and plays an essential role in vascularization of the gastrointestinal tract, probably by regulating vascular branching and/or remodeling processes in endothelial cells. In the CNS, CXCR4 could mediate hippocampal-neuron survival and is involved in cerebellar development. CXCR4 binds bacterial lipopolysaccharide (LPS) and mediates LPS-induced inflammatory response, including TNF secretion by monocytes. Antibodies to CXCR4 block HIV-1 and HIV-2 fusion and infection of human target cells. The amino-terminal domain and the second extracellular loop of CXCR4 serve as HIV biding sites.
