Scientific Data Images for Human CXCR4 Antibody

Detection of CXCR4 antibody in Human Blood Lymphocytes antibody by Flow Cytometry.

Detection of CXCR4 in Human Blood Lymphocytes by Flow Cytometry.

Human peripheral blood lymphocytes were stained with Mouse Anti-Human CD19 APC-conjugated Monoclonal Antibody (Catalog # FAB4867A) and either (A) Mouse Anti-Human CXCR4 Monoclonal Antibody (Catalog # MAB170) or (B) Mouse IgG2AIsotype Control (Catalog # MAB003) followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).

Chemotaxis Induced by CXCL12/SDF-1 alpha and Neutrali-zation by Human CXCR4 Antibody.

Chemotaxis Induced by CXCL12/SDF-1 alpha and Neutrali-zation by Human CXCR4 Antibody.

Recombinant Human/ Feline/Rhesus Macaque CXCL12/SDF-1a (Catalog # 350-NS) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR4 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human/Feline/ Rhesus Macaque CXCL12/ SDF-1a (1 ng/mL) is neutralized (green line) by increasing concentrations of Human CXCR4 Monoclonal Antibody (Catalog # MAB170). The ND50 is typically 0.3-1.2 µg/mL.

Detection of CXCR4 in Jurkat cells vs K562 by Flow Cytometry

Jurkat (filled histogram) vs K562 (open histogram) cells were stained with Mouse Anti-Human CXCR4 Monoclonal Antibody followed by Phycoerythrin-conjugated Anti-Mouse IgM Secondary Antibody (Catalog # F0116). View our protocol for Staining Membrane-associated Proteins.

Applications for Human CXCR4 Antibody

Application
Recommended Usage

CyTOF-reported

Nair, N. et al. (2016) Mucosal Immunol. 9: 68. Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Flow Cytometry

0.25 µg/106 cells
Sample: see below

Neutralization

Measured by its ability to neutralize CXCL12/SDF-1 alpha-induced chemotaxis in the BaF3 mouse pro-B cell line transfected with human CXCR4. The Neutralization Dose (ND50) is typically 0.3-1.2 µg/mL in the presence of 1 ng/mL Recombinant Human/Feline/Rhesus Macaque CXCL12/SDF-1 alpha.

Background: CXCR4

CXCR4, also known as CD184, is a G-protein-linked seven transmembrane spanning receptor that binds stromal cell-derived factor-1 (SDF-1). CXCR4 acts as a co-factor for T-cell tropic HIV-1 and -2 viral entry into cells. While primarily a membrane protein, CXCR4 undergoes trafficking and internalization in response to stimulation with phorbol esters and ligand (1). Cytoplasmic and nuclear localization of CXCR4 has been observed in colorectal and renal carcinomas (2,3) and it has been used as the basis of prognosis and metastatic state (3,4,5).
