IPTG即Isopropyl β-D-1-thiogalactopyranoside，也称Isopropyl β-D-thiogalactoside，中文名为异丙基-β-D-硫代半乳糖苷。 分子式为C 9 H 18 O 5 S，分子量为238.30，CAS Number 367-93-1，Ultra Pure，dioxane free，纯度>99%。

Isopropyl β-D-Thiogalactopyranoside (IPTG) is a molecular biology reagent used to induce gene expression in bacterial systems. It mimics lactose, binding to the lac repressor protein, leading to gene activation.

IPTG (isopropylthio-β-galactoside), a structural non-metabolizable analogue of allolactose, is an inducer of β-galactosidase activity in bacteria and is suitable for use with X-Gal or Bluo-Gal to detect lac gene activity in cloning procedures.

It is used in conjunction with X-Gal or Bluo-Gal in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli. IPTG functions by binding to the lacI repressor and altering its conformation, which prevents the repression of the β-galactosidase coding gene lacZ.

2023年11月15日 · 异丙基-β-D-硫代半乳糖苷 (IPTG) （Isopropyl β-D-thiogalactoside） 分子式: C9H18O5S. 分子量: 238.3 g/mol. 配置方法. 2g Iptg 在8ml 蒸馏水 中溶解后，定容至10ml，用0.22μm 滤器 过滤除菌，分装成1ml小份贮存于-20℃。 此时根据n（摩尔质量）=m（质量）/M（分子量）=2/238.3=0.0084 mol；将 2g 即 0.0084 mol 的iptg融入10ml水，即 c=n/v（体积）=0.0084/10=0.00084（单位mol/ml）=0.84mol/l。 之后转换为不同工作浓度就很简单了，假 …
