EXPRESSION OF PORCINE REPRODUCTIVE RESPIRATORY SYNDROME VIRUS POLYPEPTIDES IN THE SAME CELL

摘要

The present invention provides a process for the recombinant DNA production of a mature form of the PRRSV ORF 3 or ORF 4 protein. This is achieved by the co- expression of the PRRSV ORF 2, ORF 3 and ORF 4 proteins by the same cell.
