IPTG is a molecular biology reagent utilized in cloning experiments. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lacoperon. Unlike allolactose, the IPTG sulfur (S) atom creates a chemical bond which is non-hydrolyzable by the cell, preventing the cell from "eating up" or degrading the inductant; therefore the IPTG concentration remains constant.

Isopropyl β-D-1-thiogalactopyranoside, abbreviated IPTG, is a molecular biology reagent. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon.

As a core structure in many antibiotics, the beta-lactam ring is a cyclic amide. Beta-lactam antibiotics almost universally inhibit bacterial cell wall synthesis and thus induce the destruction of bacterial cells. Bacteria have evolved an enzyme that combats this antibiotic and increases resistance to death induced by antibiotic means: the beta-lactamase enzyme. Beta-lactamase enzymes can be used in a multitude...

IPTG mimics allolactase, a lac operon inducer, and is commonly used in scientific research to create proteins. It does not break down as allolactase would, keeping protein creation in steady production depending on IPTG concentration. Below are recent scientific articles that highlight some IPTG's applications in current research, and some of the future of its use. Novel sRNAS in E. coli Who: Geunu...
