  • Patent number: 11655482
    Abstract: Disclosed are a novel recombinant transition vector for increasing expression of a foreign protein in a native form without fusion partners, and a method for mass production of a foreign target protein using the same. The recombinant transition vector according to the present disclosure may allow a large amount of a foreign target protein with a high therapeutic and prophylactic value to be expressed in an insect cell. In particular, the vector may increase the expression of the foreign target protein in an own form thereof, not fused with other fusion partners. Therefore, the use of the recombinant transition vector may produce useful proteins such as antigens in insect cells at low cost and high efficiency.
