Abstract: The invention relates to uses and methods enabling the production yield of viral vectors derived from piroviruses to be improved by using DNA methylation inhibitors and/or Herpes viruses in the production of viral vectors derived from parvoviruses.

Abstract: The present invention relates to a method for producing a recombinant adeno-associated virus (rAAV), in which at different times a helper construct and also a vector construct are introduced into a suitable cell, and preferably the helper construct does not comprise, in particular with the exception of the AAV promoters, any nucleic acid sequences to which at least a Rep protein can essentially specifically bind and preferably the vector construct comprises ITR sequences in flop orientation. The recombinant adeno-associated viruses produced according to the method of the invention are suitable in particular for producing a tumor cell into which additionally nucleic acids coding for GM-CSF and B7.2 has been introduced, which in turn can be used in the form of a medicament for the treatment of cancers.

Abstract: The invention relates to host cells for packing a recombinant adeno-associated virus (rAAV). Said cells contain at least one copy of a first auxiliary construct for expressing at least one AAV Rep protein, and at least one copy of another auxiliary construct for expressing at least one AAV Cap protein. The invention also relates to auxiliary constructs for expressing at least one AAV Rep protein and one AAV Cap protein in a host cell; vector constructs comprising at least one nucleic acid which is heterologous in relation to the AAV; a method for producing a host cell for packing a recombinant adeno-associated virus (rAAV); and the use of the host cell for producing an rAAV.

Abstract: The invention relates to a method for introducing a nucleic acid into at least one cell by means of calcium phosphate (CaPi), to a method for producing a transfected cell and to the transfected cell as such.

Abstract: The invention relates to a process for separating viruses of different sizes, with the virus-containing solution preferably being filtered through one or more filter membranes.
