  • EXPRESSION VECTOR, METHODS FOR THE PRODUCTION OF HETEROLOGOUS GENE PRODUCTS AND FOR THE SELECTION OF RECOMBINANT CELLS PRODUCING HIGH LEVELS OF SUCH OF SUCH PRODUCTS
    Publication number: 20090162900
    Abstract: An expression vector for eukaryotic cells comprising a gene which codes for a protein of interest, functionally linked to a hamster-ubiquitin/S27a-promoter and a gene which codes for a fluorescent protein. Preferably the expression vector also contains an amplifiable selectable marker gene. The invention also describes host cells, preferably mammalian cells, which have been transfected with the expression vector, processes for producing heterologous gene products and a method of selecting high-producing cells.
    Type: Application
    Filed: February 15, 2008
    Publication date: June 25, 2009
    Inventors: Barbara ENENKEL, Juergen Fieder, Ralf Otto, Stefanos Grammatikos
