摘要

an expression vector for eukaryontenzellen erfindungsgemu00e4u00df is provided, at least, the following elements: $a (a) the gene for the large subunit of rna polymerase ii or mutated forms of the rna polymerase ii and the mutated forms of against - ama nitin or a derivative thereof are resistant; $a (b) nucleotide sequences.the regulation of expression of the large subunit remaining conditional statements of the amanitin resistant rna polymerase ii gene or the mutated forms; $a (c) nucleotide sequences to the selection of the vector in prokaryotes and / or eukaryotic cells; $a (d) on the replication of nucleic acid sequences of the vector in prokaryotes cells and / or eukaryotic cells; $a (e) a polyadenylierungsstelle (p(aa).
