T7 T7 EXPRESSION SYSTEM METHOD FOR ITS PRODUCTION AND USE THEREOF FOR PRODUCING RECOMBINANT PROTEINS

摘要

The invention relates to an expression system comprising a prokaryotic cell comprising a polynucleotide construct encoding a T7 RNA polymerase under the control of a T7 promoter and under the control of an inducible promoter. The present invention also relates to an expression vector comprising a gene encoding a protein to be expressed under the control of a T7 promoter, wherein the expression vector comprises a plasmid stabilizing system.
