  • Method of producing peptides using baculovirus vectors in cultured cells
    Patent number: 5110729
    Abstract: Recombinant Bombyx mori nuclear polyhedrosis viruses having, in the polyhedral protein-encoding structural gene portion of the Bombyx mori nuclear polyhedrosis virus DNA (BmNPV DNA), a structural gene for a desired protein as joined to the whole of or a part of the polyhedral protein-encoding structural gene with or without interposition of a linker base sequence are provided.By propagating the above viruses in silkworm-derived cells or silkworms, fused proteins of a desired protein and the whole of or a part of the polyhedral protein as joined together with or without interposition of a linking amino acid or peptide are produced. The desired proteins can be obtained from the fused proteins by cleavage or decomposition at the linking site.
