Abstract
A method is described for producing recombinant eukaryotic cell lines expressing multiple proteins of interest. Eukaryotic host cells are transfected with (a) a first episome which contains an EBV origin of replication and a first gene encoding a protein of interest; and (b) a second episome containing an EBV origin of replication and a second gene encoding a protein of interest. Transfected cells are obtained expressing an EBNA 1 protein. The cells are grown under conditions wherein the episomes express the first and second genes.
