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. 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).
