TOP10感受态(TOP10 Competent Cell)是一种实验室最常用的大肠杆菌感受态之一,来源于MC1061菌株,其广泛用于基因克隆、质粒转化和蓝白斑筛选等分子生物学实验。TOP10感受态生长速度较快(比DH5α快,但比Mach1-T1慢),约10 h后可见克隆。
TOP10感受态的基因型为F- mcrA Δ(mrr-hsdRMS-mcrBC) φ80 lacZΔM15 ΔlacX74 recA1 araΔ139 Δ(ara-leu)7697 galU galK rpsL (StrR) endA1 nupG。本菌株缺乏核酸内切酶(endA),能有效提高质粒DNA的产量和质量,同时本菌株为重组酶缺陷型(recA),能有效减少插入片段的同源重组概率,保证插入DNA的稳定性;而lacZΔM15则使得本菌株可以用于蓝白斑筛选;此外本菌株携带mcrA基因,当转化来自真核细胞的甲基化DNA分子时,可以优先考虑本菌株。本菌株携带的hsdR基因可用于转化通过PCR扩增得到的未甲基化DNA,StrR使得本菌株有硫酸链霉素抗性。
本产品提供即用型的TOP10化学感受态,同时提供pUC19质粒作为模板,当使用pUC19质粒(2686bp,AmpR)进行转化时,本感受态转化效率可达1 x 109 CFU/µg以上。
