Method for producing cells containing stably integrated foreign DNA at high copy number, cells produced by this method and the use of these cells to produce polypeptides encoded by the foreign DNA.

摘要

IMPROVED METHOD USING A electroporation, to produce new cells HOSTS CHARACTERIZED BY RECOMBINANT DNA stably integrated STRANGE A high copy number. RECOMBINANT HOST these cells are useful in effective large-scale production of proteins and POLIPEPRIDOS recombinants.
