产品应用

  • 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。

  • MOL 文件:367-93-1.mol
  • 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.

  • 存储注意事项:湿度敏感
  • IPTG是β–半乳糖苷酶的活性诱导物质。基于这个特性,当pUC系列的载体DNA(或其他带有lacZ 基因载体DNA)以lacZ 缺失细胞为宿主进行转化时、或用M13噬菌体的载体DNA进行转染时,如果在平板培养基中加入X–gal和IPTG,由于β–半乳糖苷酶的α–互补性,可以根据是否呈现白色菌落(或噬菌斑)而方便地挑选出基因重组体。此外,它还可以作为具有lac或tac等启动子的表达载体的表达诱导物使用。
