IL3RA antibody

Catalog No. ABIN1176902

Product Details anti-IL3RA Antibody

Target: IL3RA (Interleukin 3 Receptor, alpha (IL3RA))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This IL3RA antibody is un-conjugated

Application: Flow Cytometry (FACS), Neutralization (Neut)

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.

Immunogen: Human IL-3Ra-transfected cells

Clone: 7G3

Isotype: IgG2a kappa

Application Details

Application Notes: This antibody has been found to block the binding of 125I-IL-3 to high and low affinity IL-3 receptors and can neutralize IL-3 bioactivity. In a TF-1 cell proliferation assay, this antibody (at ~0.5 µg/ml) was found to inhibit by 50% the proliferation induced by 0.3 ng/ml (~1 U/ml) of human IL-3. In functional experiments, the 7G3 antibody was found to inhibit acute myeloid leukemia cell proliferation, basophil histamine release, endothelial cell-mediated IL-8 secretion, and neutrophil transmigration. In various formats, i.e., purified with azide (Cat. No. 554527), biotinylated (Cat. No. 554528), and phycoerythrin-labeled (Cat. No. 554529), the 7G3 antibody is useful for applications such as immunoprecipitation, Western blotting, and immunofluorescent labeling of cells for flow cytometric analysis.

Restrictions: For Research Use only

Background: Reacts with human CD123, the 70 kD IL-3 receptor alpha chain (IL-3Ralpha), which associates with the 120-140 kD beta subunit. The beta chain is shared with the receptors for interleukins IL-5 and GM-CSF. IL-3Ralpha is expressed on hematopoietic progenitors and plays an important role in hematopoietic progenitor cell growth and differentiation. This antibody has been reported to block the binding of 125I-IL-3 to high and low affinity IL-3 receptors. In functional experiments, this antibody was found to inhibit acute myeloid leukemia cell proliferation, basophil histamine release, endothelial cell-mediated IL-8 secretion, and neutrophil transmigration. This antibody has been reported to be useful for immunoprecipitation, western blot and immunofluorescent staining for flow cytometry. At the Fifth HLDA Workshop, the human IL-3 receptor was designated CD123. This antibody is routinely tested by LAL for endotoxin level and by immunofluorescent staining and flow cytometry.
