WebSolving High Basal Expression in an IPTG-inducible System. ... In addition to tight promoter control, expressing toxic proteins often requires tunable expression. Keeping expression at a desired moderate level can maximize yields by maintaining the concentration of a toxic target protein just below a host strain's tolerance. Alternatively ... WebIPTG (also known as Isopropyl-β-D-Thiogalactopyranoside) is a molecular biology reagent that functions as an inducer of galactosidase activity by binding to and inhibiting the repressor. ...
