Neutralization
Measured by its ability to neutralize CXCL12/SDF‑1 alpha -induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CXCR4. The Neutralization Dose (ND 50) is typically 8‑40 µg/mL in the presence of 10 ng/mL Recombinant Mouse CXCL12/SDF‑1 alpha.
Please Note: Optimal dilutions should be determined by each laboratory for each application. are available in the Technical Information section on our website.
Data Examples
Neutralization | Chemotaxis Induced by CXCL12/SDF‑1 alpha and Neutralization by Mouse CXCR4 Antibody. Recombinant Mouse CXCL12/SDF‑1 alpha (Catalog # ) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse 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 # ). Chemotaxis elicited by Recombinant Mouse CXCL12/ SDF‑1 alpha (10 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse CXCR4 Monoclonal Antibody (Catalog # MAB21651). The ND50 is typically 8-40 µg/mL. |
Immunocytochemistry | CXCR4 in Mouse Splenocytes. CXCR4 was detected in immersion fixed mouse splenocytes using 10 µg/mL Rat Anti-Mouse CXCR4 Monoclonal Antibody (Catalog # MAB21651) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # ) and counterstained with DAPI (blue). View our protocol for . |
Immunocytochemistry | CXCR4 in Mouse Neural Progenitor Cells. CXCR4 was detected in immersion fixed mouse neural progenitor cells using 10 µg/mL Rat Anti-Mouse CXCR4 Monoclonal Antibody (Catalog # MAB21651) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # ) and counterstained with DAPI (blue). View our protocol for . |
Immunohistochemistry | CXCR4 in Mouse Spleen. CXCR4 was detected in immersion fixed frozen sections of mouse spleen using Rat Anti-Mouse CXCR4 Monoclonal Antibody (Catalog # MAB21651) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # ) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents. View our protocol for . |

Background: CXCR4
CXCR4 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.
