大腸桿菌自誘導(dǎo)培養(yǎng)基適用于由功能性的lac操縱子(包括lac Y和lac Z)控制的表達系統(tǒng)，如PET系列參與能力。表達菌種可用BL21(DE3)技術創新。大腸桿菌自誘導(dǎo)培養(yǎng)基(E.coli Auto-Induction Medium)是在LB培養(yǎng)基的基礎(chǔ)上進行改進優(yōu)化配方集成，可用于lac調(diào)控表達的大腸桿菌菌株培養(yǎng)及蛋白表達便利性。含有多種營養(yǎng)物質(zhì)并額外添加微量元素方便、氨基酸等重要部署，碳源梯度設(shè)計既能滿足菌體生長需求不難發現，同時能實現(xiàn)外源蛋白在細菌達到飽和生長期后的自動誘發(fā)實事求是。同等產(chǎn)量相比傳統(tǒng)LB使用更少培養(yǎng)體積重要的意義，無需密切監(jiān)控菌液密度的過程(測OD)持續，且無需額外添加IPTG。本品同樣適用于多克隆表達再獲，高通量選產品和服務。產(chǎn)品為粉末形式，500g/瓶體驗區，按實驗室已經(jīng)習(xí)慣的常規(guī)LB培養(yǎng)基樣配制增多，配制方便。

LB自誘導(dǎo)培養(yǎng)基LB Broth (Auto Induction Medium)產(chǎn)品介紹選購指南

用于制備不含微量元素的LB培養(yǎng)基的固體粉末有望，添加有葡萄糖和α-乳糖進一步推進，以便在大腸桿菌中通過IPTG誘導(dǎo)的啟動子自動誘導(dǎo)蛋白表達。

Quantity: 500g

Appearance: Beige powder. Autoclaved medium should be amber.
