  • Patent number: 12344856
    Abstract: Provided are a preparation method and system for a recombinant adeno-associated virus (rAAV) and a recombinant bacmid. The method comprises: first reconstructing a recombinant bacmid containing a recombinant baculovirus genome that produces essential functional elements for an rAAV, at least one of the essential functional elements being inserted into the N-terminal or C-terminal of a locus of an essential gene of the recombinant baculovirus genome; and then transfecting the obtained recombinant bacmid containing the recombinant baculovirus genome that produces the rAAV into a host cell line for culturing to prepare an rAAV. Compared with recombinant baculoviruses obtained by conventional Tn7 recombinant preparations of recombinant bacmid, the recombinant baculovirus obtained by inserting a core element containing Cap, Rep and ITR into two sides of a baculovirus essential gene has a more stable rAAV serial passage production level in a cell and has a higher rAAV yield.
