Common beta Chain Antibody (BION-1) - Azide and BSA Free Summary

• Description: Novus Biologicals Mouse Common beta Chain Antibody (BION-1) - Azide and BSA Free (NBP3-09024) is a recombinant monoclonal antibody validated for use in IHC, WB and IP. All Novus Biologicals antibodies are covered by our 100% guarantee.
• Additional Information: Recombinant Monoclonal Antibody
• Immunogen: BALB/c mice were immunized intraperitonally with COS cells transfected DQP (Domain 4 of the common beta-chain) expression constructs. The immunizations were repeated 4 times at 2-week intervals. Four weeks after the final immunization, a mouse was boosted with COS transfectants intravenously. Three days later, splenocytes were harvested and fused with NS-1 myeloma cells. Hybridoma supernatants were screened on CHO DQP cells by flow cytometry, with untransfected CHO cells as a control. All antibodies were from single hybridoma clones as selected by a limiting dilution method. MoAbs were purified from ascites fluid or hybridoma supernatant by a protein A sepharose column.
• Specificity: Binds to domain 4 of the common beta-chain and recognises the same binding site used by IL-5, GM-CSF and IL-3, or binds to an epitope in close proximity to it. Residues M363, R364, E366 (B-C loop) and R418 (F-G loop) in the common beta-chain are important for BION-1 binding.
• Isotype: IgG1 Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: CSF2RB
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • Block/Neutralize

• Application Notes: This reformatted mouse antibody was made using the variable domain sequences of the original Mouse IgG format, for improved compatibility with existing reagents, assays and techniques.
  
  BION-1 has been shown the block eosinophil production, survival, and activation stimulated by IL-5 as well as by GM-CSF and IL-3, thereby influencing inflammation (Sun 1999). Further, BION-1 has been used in immunohistochemistry experiments in order to examine the presence of GM-CSF-receptor protein in human 8-cell embryos and blastocysts (Sjoblom 2002). In addition, a fab fragment derived from BION-1 has been used in the crystallisation of the common beta-chain to analyse the structure of the activation domain of the GM-CSF/IL-3/IL-5 receptor (Rossjohn 200).

Background

Interleukin-3 receptor (IL-3R) is a heterodimer cytokine composed of alpha chain and beta chain. IL-3R beta subunit (CD131, beta C) is a common shared beta chain of the receptor for granulocyte- macrophage colony-stimulating factor (GM-CSF) and IL-5 (1). While the beta chain can not bind to the ligand alone, but it is essential for high affinity ligand binding (2). The cytoplasmic portion of the beta chain contains the major domains necessary for ligand-induced proliferation (3). IL-3R beta is expressed in neutrophil, eosinophil, monocyte, and hematpoietic stem cells. A point mutation leading to defective IL-3R beta expression has been associated to Human pulmonary alveolar proteinosis (PAP), a rare cause of respiratory failure (4).
