Quick Overview for CXCR4 antibody (ABIN1177332)

Target: CXCR4 (Chemokine (C-X-C Motif) Receptor 4 (CXCR4))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CXCR4 antibody is un-conjugated

Application: Flow Cytometry (FACS)

Clone: 12G5

Product Details anti-CXCR4 Antibody

Brand: BD Pharmingen™

Purification: The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Sterility: 0.2 μm filtered

Endotoxin Level: Endotoxin level is ≤ 0.01 EU/μg (≤ 0.001 ng/μg) of protein as determined by the LAL assay.

Isotype: IgG2a kappa

Application Details

Application Notes: Flow cytometry: Chemokine receptors are known to internalize during manipulation resulting in low frequency expression. Investigators are advised to perform immunophenotyping studies of chemokine receptors on freshly collected samples (<24 Hrs). Incubation with the antibody should be done at 4°C in the dark. Cellular manipulation, such as Ficoll separation, freezing, or exposure to cold temperatures prior to staining should be minimized and have been shown to cause a decrease in staining intensity and/or inconsistent results. Investigators should note that alternative staining procedures may be neccessary. A multiple-step staining procedure is strongly recommended, in some instances, to amplify immunofluorescent signals for the flow cytometric analysis of human CXCR4 expression. Investigators may find the Purified NA/LE Mouse Anti-Human CD184 antibody to be useful in conjunction with appropriate secondary and tertiary reagents for detecting low frequency expression, such as with Biotin Goat Anti-Mouse Ig (MN 553999) and PE Streptavidin (MN 554061).

Target Details for CXCR4

Target: CXCR4 (Chemokine (C-X-C Motif) Receptor 4 (CXCR4))

Alternative Name: CD184

Background: Reacts with fusin (CXCR4), a seven-transmembrane domain, G-protein-linked glycoprotein. Fusin is expressed on a wide variety of CD4+ and CD4- cells including those from spleen, brain and lung. It has been shown to function as a cofactor for infection with T-cell tropic strains of HIV-1 and also as a receptor for CD4-independent infection. 12G5 antibody has been reported to block CD4-independent infection by HIV-2 and CD4-dependent infection by some T-cell tropic isolates of HIV-1.
Synonyms: CXCR4 (Fusin)
