Technological Context And Concerns

Descriptif

For manufacturing recombinant proteins or DNA, plasmid instability is a significant concern. Typical biomanufacturing processes in prokaryotes require the use of bacterial plasmids as vectors carrying the gene of interest to be over-expressed. It has been demonstrated that the growth of plasmid bearing cells is significantly reduced relative to plasmid free hosts, simply because protein production represents a significant burden on cellular metabolism. This is of significant concern in the Biopharmaceutical Industry as both the yield and the production reproducibility of recombinant molecules are significantly lowered by that fact. Antibiotic resistance genes are the most common selectable markers used in fermentation processes to avoid plasmid free cells to overgrow the culture. However antibiotics are expensive compounds and they (or their degradation products) can contaminate the biomass or production product.
