产品简介:本产品是一种来源于 E. coli K-12的菌株,是目前生长速度最快的克隆用大肠杆菌菌株,在平板上37℃,7 h可见克隆。是主要的噬菌体展示用菌株,同时也可用于普通质粒的构建,lacIq ZΔM15的存在使其可以用于蓝白斑筛选等实验;但不含核酸酶endA1突变,体内核酸酶含量较高,提取质粒时务必使用质粒提取试剂盒中去蛋白液尽量去除核酸酶,以防提取的质粒被降解。本产品经优化的感受态制备工艺制备而成,使用pUC19质粒DNA检测,转化效率高达1×10⁹cfu/µg。
产品应用:
♦ 本产品适用于噬菌体展示和克隆构建;
♦ 适用于蓝白班筛选。
产品特点:
♦ 生长速度快,转化效率高达1×10⁹cfu/μg。
