Production and characterisation of monoclonal antibodies specific for chicken interleukin-12
Using genetic immunisation of mice, we produced antibodies against chicken interleukin-12p40 (chIL-12p40), also known as IL-12 beta. After a final injection with a recombinant chIL-12p40 protein, several stable hybridoma cell lines were established which secreted monoclonal antibodies (mAbs) to this component of the heterodimeric IL-12 cytokine. Specific binding of three of the mAbs to COS-7 cell-derived recombinant chIL-12p40 and the chIL-12p70 heterodimer was demonstrated in an indirect ELISA, and in dot blots. Two of the mAbs were used to develop a capture ELISA, suitable for detecting both recombinant protein (chIL-12p40 and the heterodimeric p70 protein) and native chIL-12. The mAbs were further characterised to show utility in immunocytochemistry.
