VSV rescue

Abstract

The present invention relates to a method for rescue of Vesicular Stomatitis Virus (VSV) from DNA in a HEK293 cell line or a HEK293 cell line adapted to suspension growth comprising (a) providing cells from a HEK293 cell line or a HEK293 cell line adapted to suspension growth in cell culture, (b) transfecting the cells with at least one plasmid, wherein the at least one plasmid comprises (i) an expression cassette comprising a VSV genomic cDNA; (ii) at least one expression cassette encoding VSV nucleoprotein (N) protein, VSV phosphoprotein (P) protein, and VSV large (L) protein; and (iii) an expression cassette encoding SV40 Large T antigen; (c) culturing the transfected cells; and (d) harvesting the cell culture supernatant comprising the rescued VSV. Also provided is the use of a HEK293 cell line or a HEK293 cell line adapted to suspension growth for rescue of Vesicular Stomatitis Virus (VSV) or the use of a plasmid encoding SV40 Large T antigen for rescue of Vesicular Stomatitis Virus (VSV) in a HEK293 cell line or a HEK293 cell line adapted to suspension growth HEK293-F cells by means of transient transfection.
