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 … Webthiogalactoside (IPTG) and o-nitrophenyl-1- -D-fucoside (ONPF). IPTG is a gratuitous inducer of the lac operon - it induces expression even ... but IPTG causes the repressor to release from the operator, whereas ONPF prevents induction by preventing the repressor from releasing from the operator even in the presence of an inducer.
WebIPTG is an effective inducer of protein expression in the concentration range of 100 μmol/L to 3.0 mmol/L. Typically, a sterile, filtered 1 mol/L solution of IPTG is added 1:1000 to an …
