WebNov 28, 2024 · The best inducer concentrations were determined to be between 0.05 and 0.1 mM IPTG for all investigated temperatures. This is 10–20 times lower than conventional guidelines suggest. The induction time was less relevant when the correct inducer concentration was chosen. WebMay 10, 2024 · Isopropyl β-D-1-thiogalactopyranoside (IPTG, also known as lad-y) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce E.coli protein expression where the gene is under the control of the lac operator.

Practical protocols for production of very high yields of …

WebTo efficiently induce gene expression, a sufficient dosage of an inducer, usually that of 500-1000 µM isopropyl β-D-1-thiogalactopyranoside (IPTG), is required to keep repressor LacI from its binding sites, which is a heavy cost burden in low-value-added products. WebIPTG (Isopropyl ß-D-1-thiogalactopyranoside), is a molecular biology reagent. This compound 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.

This promoter is regulated by the endogenous E. coli lacI protein and is induced with IPTG. IPTG is required to induce expression of the T7 RNA polymerase.

WebIPTG (isopropylthio-β-galactoside) is an inducer of β-galactosidase activity in bacteria and is suitable for use with X-gal or bluo-gal to detect la c gene activity during cloning. Life Technologies offers IPTG in several sizes for added convenience. Ordering Information WebDue to the presence of a sulfur atom in IPTG, the cells cannot degrade the inducer and therefore its concentration remains constant. IPTG (isopropyl beta-D-thiogalactoside) Inducer for Beta-Galactosidase Expression is ideal for investigators in Immunology, Cell Biology, and Microbiology research. Application Note
