367-93-1 - Application:

Isopropyl-β-D-Thiogalactopyranoside (IPTG) (CAS: 367-93-1) is a molecular biology reagent that functions as an inducer of galactosidase activity by binding to and inhibiting the repressor. It is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator. IPTG cannot be hydrolyzed or broken down by the E. coli therefore the concentration remains constant during cell replication. IPTG is often used at a final concentration ranging from 0.5-1.0 mM. X-Gal is often used with IPTG since it provides an easy visual method to monitor whether protein expression has occurred. X-Gal as the name implies contains a galactose group that once metabolized causes a bright blue color change.
IPTG is an effective inducer of protein expression in the concentration range of 100 μM to 1.0 mM. Concentration used depends on the strength of induction required, as well as the genotype of cells or plasmid used. If lacIq, a mutant that over-produces the lac repressor, is present, then a higher concentration of IPTG may be necessary.
Commonly used molecular biological reagents, such as blue and white spot screening and IPTG induced protein expression in bacteria, etc.
