蛋白质纳米孔作为快速、低成本 DNA 分子测序平台的关键组成部分正在接受研究。此前已有研究表明,α-溶血素 (αHL) 纳米孔含有三个识别位点,当寡核苷酸固定在纳米孔内时,能够区分单个 DNA 碱基。然而,RNA 的直接测序也至关重要。在这里,我们实现了清晰的电流分布,能够清楚地区分 RNA 中的四种核碱基:鸟嘌呤、胞嘧啶、腺嘌呤和尿嘧啶。此外,可以区分修饰的碱基肌苷、N6-甲基腺苷和N5-甲基胞嘧啶。
Protein nanopores are under investigation as key components of rapid, low-cost platforms to sequence DNA molecules. Previously, it has been shown that the α-hemolysin (αHL) nanopore contains three recognition sites, capable of discriminating between individual DNA bases when oligonucleotides are immobilized within the nanopore. However, the direct sequencing of RNA is also of critical importance. Here, we achieve sharply defined current distributions that enable clear discrimination of the four nucleobases, guanine, cytosine, adenine and uracil, in RNA. Further, the modified bases, inosine, N6-methyladenosine and N5-methylcytosine, can be distinguished.
