Background Interleukin-4 (IL-4) is a monomeric 20 kDa predominantly produced by activated T lymphocytes of the Th2 phenotype, by mast cells and by some antigen-presenting cells. Together with IL-2, IL-4 is an autocrine growth factor for activated T cells and for cytotoxic T cell precursors. IL-4 is a major factor involved in the activation of resting B lymphocytes. Together with IL-13, IL-4 induces isotype switch towards IgE and IgG1 isotypes. 11B4, was produced from a rat immunized with purified human IL4-transfected-COS7 cells. It recognized both E. coli-expressed and mammalian cell-expressed (COS7 and L cell), rhuIL-4 in solution (immunoprecipitation), as well as on solid phase (indirect ELISA and dot-blotting). The 11B4 antibody inhibited IL-4 bioactivity at an IC50 which was 25-50-fold in molar excess of factor. The 11B4 antibody was used to develop an immunoenzymatic assay capable of detecting concentrations less than 100 pg/ml. (Chrétien I et al, 1989, J. Immunol. Methods, 1178 (1) : 67-81; Ramanathan L.et al, 1993, Biochemistry, 32 (14) :3549-56).
