WebIPTG 是一种 分子生物学 试剂，全称 异丙基-β-D-硫代半乳糖苷 （英語： Isopropyl β-D-1-thiogalactopyranoside ），是 異乳糖 的 结构类似物 ，能与 乳糖抑制子 结合，高效启动 乳糖操縱子 （ lac operon）的 转录 ，来表达操縱子中的目的 基因 [1] 。 参考文献 [ 编辑] ^ Hansen LH, Knudsen S, Sørensen SJ. The effect of the lacY gene on the induction of IPTG … WebIPTG is a reagent which mimics the structure of allolactose, and can therefore bind to the lac repressor and prevent it from inhibiting gene expression. Once enough IPTG is added, the T7 gene is normally transcribed and so transcription of the gene of interest downstream of the T7 promoter also begins. [6]
