Abstract
A method for expressing recombinant molecules in bacterial hosts in a defined medium in the absence of antibiotic selection is disclosed. The method uses an expression vector comprising a regulatable promoter by which the production of foreign proteins may be controlled during the growth phase of the culture, and origin of replication maintaining medium vector copy number and a transcriptional promoter.
