正品|IPTG|Isopropyl-β-D-thiogalactopyranoside|异丙基-β-D-硫代半乳糖苷|
货号: 420322 产品名称: 正品|IPTG|Isopropyl-β-D-thiogalactopyranoside|异丙基-β-D-硫代半乳糖苷| 品牌: Merck 规格: 10g分 大量现货
中文品名: 异丙基-β-D-硫代半乳糖苷
英文名: Isopropyl β-D-1-Thiogalactopyranoside
英文简称: IPTG
产品性状: 白色或白色粉末,溶于水后呈清亮无色液体
保存温度: 2-8°C冷藏保存 ,配制好后保存于-20°C,
主要作用:异丙基硫代半乳糖苷(IPTG)是一种作用极强的诱导剂,不被细菌代谢而十分稳定,因此被实验室广泛应用
说明:
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。
