| 应用 | IPTG 常用于需要诱导 β-半乳糖苷酶活性的克隆实验。它常与 X-Gal 或 Bluo-Gal 结合使用，用于重组细菌菌落的蓝白筛选，这些菌落可以诱导 lac 操纵子在大肠杆菌中的表达。IPTG 与 lacI 阻遏蛋白结合并改变其构象而发挥作用，防止 β-半乳糖苷酶编码基因 lacZ 的抑制。 |
| 产品介绍 | IPTG, Dioxane-Free (isopropyl-β-thiogalactoside) is an analogue of allolactose that binds specifically to the repressor protein of the lac operon and induces expression of β-galactosidase in Escherichia coli. The compound is widely used with X-Gal plates to screen for blue and white colonies. The lac operon system and IPTG have been used in multiple cloning experiments and cellular systems to study gene activity. |
