IPTG Isopropyl β-D-thiogalactoside CAS:367-93-1
IPTG is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.
IPTG uptake by E. coli can be independent of the action of lactose permease, since other transport pathways are also involved. At low concentration, IPTG enters cells through lactose permease, but at high concentrations (typically used for protein induction), IPTG can enter the cells independently of lactose permease[1].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
IPTG异丙基β-D-硫代半乳糖苷CAS:367-93-1
异丙基-β-D-硫代半乳糖苷是一种有机物，化学式为C9H18O5S，是异乳糖模拟物，能够引起乳糖操纵子的转录过程，因此能够诱导乳糖操纵子下游基因对应蛋白的表达。
