Expression vector for animal cell containing nuclear matrix attachment region of interferon beta

Abstract

The present invention relates to mammalian expression vectors including nuclear matrix attachment region of human interferon β, and more particularly to pPGM-1, pPGM-2 and pPGM-3 including nuclear matrix attachment region of interferon β gene. Those expression vectors confer position independent expression of the introduced foreign gene, thus increasing the frequency of colonies which efficiently express the recombinant protein.
