title: Production and characterisation of monoclonal antibodies to ovine interleukin-5.
abstract: Monoclonal antibodies (MAbs) were developed against recombinant ovine interleukin-5 (IL-5) produced in the baculovirus expression vector system. One MAb, D11 (isotype IgG1), neutralised the activity of both recombinant and native sources of IL-5 in a biological assay (Baf cell assay) but was only weakly reactive in immunocytochemistry. Conversely, a second MAb, A8 (isotype IgA), successfully detected IL-5 in immunocytochemistry but did not display neutralising activity. The development of these MAbs will enable the assay of ovine IL-5 in vitro and permit studies into the role of hypersensitivity reactions in sheep by neutralisation of IL-5 in vivo.
