title: Cross reactions between porcine, bovine and ovine interleukin-2 preparations.
abstract: Optimum conditions for the production of porcine interleukin-2 were found to include a delay of 24 hours before the addition of mitogen. Porcine and bovine interleukin-2 responded optimally in homologous systems whereas bovine interleukin-2 gave a better response in the ovine system than homologous ovine interleukin-2. Interleukin-2 produced from a continuous gibbon cell line reacted well with porcine, ovine and bovine T cell blasts indicating that it could act as a universal growth factor for T cell clones produced from these species.
