WebSolving High Basal Expression in an IPTG-inducible System High uninduced expression of a target protein can seriously hamper a host strain's viability or result in loss of plasmid from a significant share of the cell population. Many commercial plasmids and host strains can provide regulated expression to reduce or eliminate this problem. hinge failure
