  • Heat-resistant newcastle disease virus live vaccine vector system and use thereof
    Patent number: 9051584
    Abstract: A heat-resistant NDV live vaccine vector system includes a transcription plasmid, three helper plasmids, and host cells. The transcription plasmid is constructed by through cloning complete genomic cDNA of a heat-resistant NDV vaccine strain to a pBR322 vector. The three helper plasmids are constructed by cloning sequences coding nucleoprotein (NP), phosphoprotein, large polymerase protein of a heat-resistant NDV vaccine strain respectively to pcDNA3.1 vectors. A recombinant NDV artificially obtained by cotransfacting host cells with the transcription plasmid and the three helper plasmids shows heat-resistance.
