中文品名: 異丙基-β-D-硫代半乳糖苷
英文名: IPTG,Isopropyl β-D-1-Thiogalactopyranoside
保存溫度: 2-8°C冷藏保存 ,配制好后保存于-20°C,
主要作用:異丙基硫代半乳糖苷(IPTG)是一種作用極強(qiáng)的誘導(dǎo)劑,不被細(xì)菌代謝而十分穩(wěn)定,因此被實(shí)驗(yàn)室廣泛應(yīng)用
說明:
IPTG是β–半乳糖苷酶的活性誘導(dǎo)物質(zhì)�;谶@個(gè)特性,當(dāng)pUC系列的載體DNA(或其他帶有l(wèi)acZ 基因載體DNA)以lacZ 缺失細(xì)胞為宿主進(jìn)行轉(zhuǎn)化時(shí)、或用M13噬菌體的載體DNA進(jìn)行轉(zhuǎn)染時(shí),如果在平板培養(yǎng)基中加入X–Gal和IPTG,由于β–半乳糖苷酶的α–互補(bǔ)性,可以根據(jù)是否呈現(xiàn)白色菌落(或噬菌斑)而方便地挑選出基因重組體。此外,它還可以作為具有l(wèi)ac或tac等啟動(dòng)子的表達(dá)載體的表達(dá)誘導(dǎo)物使用。
