A major molecular determinant of virus host-range is thought to be the viral protein required for cell attachment. We used a recombinant strain of Rinderpest virus (RPV) to examine the role of this protein in determining the ability of RPV to replicate in rabbits. The recombinant was based on the RBOK vaccine strain, which is avirulent in rabbits, carrying(More)
We produced four monoclonal antibodies (mAb) and two polyclonal antibodies using the purified cytokine expressed in bacteria and characterized them. Specific binding of each of the mAb and polyclonal antibodies to recombinant swine IL-4 (rSwIL-4) purified from Escherichia coli and baculovirus was demonstrated in an indirect ELISA and/or in western blotting.(More)
The in vitro effect and the in vivo influence of recombinant swine IL-4 (rSwIL-4) were characterized in various swine cells and in nursery pigs on LPS-induced endotoxic shock and pro-inflammatory cytokine productions. In in vitro experiment, the rSwIL-4 induced a proliferation of CD4 positive T cells in mitogen-prestimulated peripheral blood mononuclear(More)
The swine interleukin-4 (SwIL-4) cDNA was cloned by RT-PCR. It was expressed using an expression vector pQE30 in E. coli, a baculovirus AcNPV vector pVL1392 in insect cells, and a pCAGGS vector in mammalian cells. The rSwIL-4 proteins expressed from bacteria and insect cells were purified using a chelating affinity column and a mAb-coupled immunoaffinity(More)
The swine interleukin-6 (SwIL-6) cDNA was cloned by RT-PCR and each expression system of recombinant SwIL-6 in Escherichia coli, insect cells, and mammalian cells was developed. Recombinant SwIL-6 produced in bacteria was applied for generation of the polyclonal antibodies. The rSwIL-6 was purified from supernatant of insect cells with a Q-sepharose or(More)
We established a sandwich enzyme-linked immunosorbent assay (ELISA) for swine interleukin-6 (SwIL-6), which was applied for detection of SwIL-6 in vitro and in vivo. Anti-SwIL-6 rabbit- and goat-polyclonal antibodies, and monoclonal antibody (mAb) were prepared, conforming that all of the antibodies were reactive with recombinant SwIL-6 by Western blotting(More)
