ABSTRACT:
A transformation vector containing a heterologous product gene and two or more different heterologous selectable amplifiable marker genes is described. Preferably, the marker genes form a polycistronic transcription unit. Also described is a method for obtaining high level expression of a desired protein by culturing eukaryotic cells containing the vectors of the invention.
