	Western Blot: CXCR4 Antibody [NB100-56437] - Analysis using the Azide Free version of NB100-56437. Detection of 15 ug of Detection of HeLa cells with anti-CXCR4 at 1 ug/ml.
	Immunocytochemistry/Immunofluorescence: CXCR4 Antibody [NB100-56437] - Jurkat cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton-X100. The cells were incubated with anti-CXCR4 (NB100-56437) at a 1:25 dilution for 1 hour at room temperature and detected with an anti-rabbit Dylight 488 (Green) at a 1:500 dilution. Alpha tubulin was used as a co-stain at a 1:1000 dilution and detected with and anti-mouse Dylight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.
	Immunohistochemistry-Paraffin: CXCR4 Antibody [NB100-56437] - CXCR4 was detected in immersion fixed paraffin-embedded sections of human tonsil using rabbit anti-human antibody (Catalog # NB100-56437) at 1:300 dilution overnight at 4C. Tissue was stained using the VisuCyte anti-rabbit HRP polymer detection reagent (Catalog # VC003) with DAB chromogen (brown) and counterstained with hematoxylin (blue).Images may not be copied, printed or otherwise disseminated without express written permission of Novus Biologicals a bio-techne brand.

Background

Human immunodeficiency virus (HIV) and related viruses require coreceptors, in addition to CD4, to infect target cells. Some G protein-coupled receptors including CCR5, CXCR4, CCR3, CCR2b and CCR8 in the chemokine receptor family, and four new human molecules GPR15, STRL33, GPR1 and V28 were recently identified as HIV coreceptors1. Among them, CXCR4 (fusin, LESTR or HUMSTR) is a principal coreceptor for T-cell tropic strains of HIV-1 fusion and entry of human white blood cells (2,3). CXCR4 is also required for the infection by dual-tropic strains of HIV-1 and mediates CD-4 independent infection by HIV-2 (4,5). The a-chemokine SDF-1 is the ligand for CXCR4 and prevents infection by T-tropic HIV-1 (6,7). CXCR4 associates with the surface CD4-gp120 complex before HIV enters target cells (8). CXCR4 messenger RNA levels correlated with HIV-1 permissiveness in diverse human cell types (2). Antibodies to CXCR4 block HIV-1 and HIV-2 fusion and infection of human target cells (2,5,10). The amino-terminal domain and the second extracellular loop of CXCR4 serve as HIV biding sites (10,11).
