  • Publication number: 20220195456
    Abstract: Aspects of the disclosure relate to a nucleic acid comprising a heterologous nucleic acid insert flanked by interrupted self-complementary sequences, wherein one self-complementary sequence is interrupted by a cross-arm sequence forming two opposing, lengthwise-symmetric stem-loops, and wherein the other of the self-complementary sequences is interrupted by a truncated cross-arm sequence. Methods of delivering the nucleic acid to a cell are also provided.

  • Publication number: 20210348194
    Abstract: The present disclosure describes methods and systems for use in the production of adeno-associated virus (AAV) particles, including recombinant adeno-associated virus (rAAV) particles. In certain embodiments, the production process and system use Spodoptera frugiperda insect cells (such as Sf9 or Sf21) as viral production cells. In certain embodiments, the production process and system use Baculoviral Expression Vectors (BEVs) in the production of AAV particles. In certain embodiments, the production process and system uses an engineered nucleic acid construct which encodes for AAV capsid proteins, such as VP1, VP2 and VP3. In certain embodiments, the production process and system uses an engineered nucleic acid construct which encodes for AAV replication proteins, such as Rep78 and Rep52.

  • Publication number: 20210301305
    Abstract: The present disclosure describes methods and systems for use in the production of recombinant adeno-associated virus (rAAV) particles. In certain embodiments, the production process and system include engineered untranslated regions (UTR) which allow for the controlled expression of AAV capsid proteins, such as VP1, VP2 and VP3. In certain embodiments, the production process and system include engineered untranslated regions (UTR) which allow for the controlled expression of non-structural AAV replication proteins, such as Rep78 and Rep52.
