Quick Overview for Recombinant IL3RA antibody (ABIN7487683)

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

Antibody Type: Recombinant Antibody

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This IL3RA antibody is un-conjugated

Application: Flow Cytometry (FACS), Western Blotting (WB), Immunoprecipitation (IP), Blocking Reagent (BR)

Clone: 7G3

Product Details anti-IL3RA Antibody

Purpose: Anti-CD123 [7G3], Mouse IgG2a, kappa

Specificity: This antibody specifically binds to the IL-3R alpha-chain and completely abolishes its function. IL-3R is expressed on myeloid, lymphoid, and vascular endothelial cells, where it transduces IL-3-dependent signals leading to cell activation.

Characteristics:

Original Species of Ab: Mouse

Original Format of Ab: IgG2a

Purification: Protein A affinity purified

Immunogen: The original antibody was generated by intraperitoneally immunizing BALB/c mice with 5 X lo6 COS cells transfected with the IL-3R a-chain in combination with adjuvant peptides.

Isotype: IgG2a kappa

Application Details

Application Notes: This antagonist antibody binds IL-3Rα and blocks IL-3 binding and IL-3-mediated functions. mAb 7G3 immunoprecipitated and recognized in western blots the IL-3R α chain expressed by transfected cells and bound to primary cells expressing IL-3Rα. The expression of IL-3Rα chain on various cells types was analysed by flow cytometry using this antibody (PMID: 8547680). It is reported that 7G3 inhibits IL-3Rα and βc dimerization (PMID: 8649415). This antibody was used in the study of neutrophils expressing IL-3 receptors which are activated by granulocyte-macrophage colony-stimulating factor or GM-CSF (PMID: 7579364). The original 7G3, mouse IgG2a antibody inhibited IL-3-mediated intracellular signaling of isolated acute myeloid leukemia (AML) CD34+ CD38- cells in vitro and reduced their survival (PMID: 19570512). Humanized version of this antibody CSL362 is available on request. CSL362, retains the ability to neutralise IL-3 and has enhanced affinity for the FcγRIIIa (CD16) on NK cells. In vitro studies have demonstrated that the increased affinity for CD16 correlates with greater antibody-dependent cell-mediated cytotoxicity (ADCC) against CD123 expressing cell lines (Busfield et al., 2012). CSL362 is being accessed for use in the treatment of myeloid leukemia (PMID: 24363400, 2524888, 26130514).
