Human CXCR4 Antibody Summary

Species Reactivity
Reacts specifically with human and non-human cells expressing human CXCR4 (fusin) as detected by flow cytometry. It will also react with cells expressing feline CXCR4 but not rat CXCR4. This antibody does not cross-react with other chemokine receptors.
Monoclonal Mouse IgG2B Clone # 44717
Protein A or G purified from hybridoma culture supernatant
3T3 cells transfected with human CXCR4
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Recommended Concentration
Flow Cytometry
2.5 µg/106 cells
Jurkat human acute T cell leukemia cell line
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
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 1-5 µg/mL in the presence of 1 ng/mL Recombinant Human/Feline/Rhesus Macaque CXCL12/SDF‑1 alpha.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Chemotaxis Induced by CXCL12/SDF‑1 alpha and Neutralization 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 Mouse Anti-Human CXCR4 Monoclonal Antibody (Catalog # MAB173). The ND50 is typically 1-5 µg/mL.

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).
