CH-2026-04-29Isopropyl β-D-1-thiogalactopyranoside (IPTG) is a synthetic analog of lactose widely used as a molecular biology reagent for the induction of gene expression. It functions as a gratuitous inducer of the lac operon in bacteria such as E. coli by binding to the lac repressor and enabling transcription of downstream genes.
Unlike lactose, IPTG is not metabolized by cells, which allows for stable and sustained induction of recombinant protein expression. It is commonly used in conjunction with vectors containing lac promoter or T7-lac hybrid systems.
This product is dioxane-free, ensuring higher purity and suitability for sensitive biological applications.
