METHODS AND COMPOSITIONS FOR EXPRESSING NEGATIVE-SENSE VIRAL RNA IN CANINE CELLS RNA

摘要

The present invention provides novel canine pol I regulatory nucleic acid sequences useful for the expression of nucleic acid sequences in canine cells such as MDCK cells. The invention further provides expression vectors and cells comprising such nucleic acids as well as methods of using such nucleic acids to make influenza viruses, including infectious influenza viruses.
