  • Publication number: 20070026521
    Abstract: Accessory functions capable of supporting efficient recombinant AAV (rAAV) virion production in a suitable host cell are provided. The accessory functions are in the form of one or more vectors that are capable of being transferred between cells. Methods of producing rAAV virions are also provided. The methods can be practiced to produce commercially significant levels of rAAV particles without also generating significant levels of infectious helper virus or other contaminating by-products.

  • Publication number: 20050276787
    Abstract: One form of a composition has two types of recombinant adeno-associated virus. The first type encodes a portion of Factor VIII operably linked to an expression control element; and the second type encodes a different portion of Factor VIII operably linked to an expression control element. The first and second nucleotide sequences collectively encode a functional Factor VIII protein. Another form of the composition is a recombinant adeno-associated virus containing a nucleotide sequence encoding functional Factor VIII light or heavy chain operably linked to a tissue-specific promoter.
