一般描述
异丙基 β-D-硫代半乳糖苷 (IPTG) 是一种分子生物学试剂，用于诱导细菌系统中的基因表达。它模仿乳糖，与 lac 阻遏蛋白结合，导致基因激活。IPTG 对于研究基因调控、蛋白质表达和重组蛋白质生产至关重要，为细胞和分子生物学研究提供了宝贵的见解。
应用
IPTG 可用于：
- 诱导罗伊氏乳杆菌 GroEL 和突变体中的蛋白质表达
- 在大肠杆菌中诱导蛋白质表达
IPTG通常用于需要诱导β-半乳糖苷酶活性的克隆程序。它与 X-Gal 或 Bluo-Gal 一起用于重组细菌菌落的蓝白斑筛选，其诱导 lac 操纵子在大肠杆菌中的表达。IPTG 通过与 lacI 阻遏物结合，并改变其构象起作用，其阻止 β-半乳糖苷酶编码基因 lacZ 的阻遏作用。
生化/生理作用
IPTG 是异乳糖的不可代谢类似物。它作为诱导子调节 lac 启动子的转录活性，该启动子用于在大肠杆菌中表达该蛋白质。
重悬
将 IPTG 溶于水，然后经无菌过滤，配制成储存液 (0.1M)。指示板中 IPTG 最终浓度应为 0.2mM。

We previously showed that supernatants of Lactobacillus biofilms induced an anti-inflammatory response by affecting the secretion of macrophage-derived cytokines, which was abrogated upon immunodepletion of the stress protein GroEL. We purified GroEL from L. reuteri and analysed its anti-inflammatory properties
