IPTG (Isopropyl β-D-1-thiogalactopyranoside), Dioxane-Free – High-Purity 
Inducer for Molecular Biology
Isopropyl β-D-1-thiogalactopyranoside (also known as Isopropyl β-D-thiogalactoside or IPTG) is a widely used molecular biology reagent, primarily employed as an inducer for the lac operon in gene expression studies. Known for its stability, high solubility, and effectiveness, IPTG plays a crucial role in optimizing protein expression in Escherichia coli (E. coli) and other bacterial systems.
Our IPTG is high-purity and completely dioxane-free, ensuring safety, reliability, and consistent performance for research applications. Every batch is manufactured under strict quality controls and supplied with a Certificate of Analysis confirming purity and the absence of dioxane.
