  • Patent number: 10344293
    Abstract: A recombinant vector for transforming a plant, a plant transformed with the recombinant vector, a plant-made classical swine fever virus antigen pmE2 protein expressed in the plant and uses thereof is provided. By using a recombinant vector having a polynucleotide encoding a GP55 protein of CSFV according to the present invention; and a polynucleotide encoding a cellulose-binding domain protein; and a plant transformed with the recombinant vector, a plant-made classical swine fever virus antigen pmE2 protein may be produced with high efficiency, and has higher safety and stability than those achieved by other production methods. Also, since the plant-derived classical swine fever virus antigen protein pmE2 has a cellulose-binding domain (CBD) protein, it may be usefully used as an effective marker to determine a virus exposure pathway and an antibody producing pathway.
