    • Provided are methods of nucleic acid sample preparation for analysis, including analysis using nanopore sequencing applications. In particular provided are methods that allow for the creation of circular and linear DNA samples that contain asymmetric ends to ligate different and desired adaptors to the end of the sample, methods to create single nucleic acid molecules that automatically form concatemers for higher sequencing throughput; methods to create multiple copies (temperature dependent, multi-primed, open-fold replication) of one original nucleic acid sample, or to create single nucleic acid molecules containing multiple copies of more than one original nucleic acid sample (concatemerized samples) for improved accuracy and throughput are described; and methods for improved modified base calling.
    • 提供用于分析的核酸样品制备方法,包括使用纳米孔测序应用的分析。 特别提供了允许产生含有不对称末端以将不同和所需衔接子连接到样品末端的环状和线性DNA样品的方法,产生单一核酸分子的方法,所述单个核酸分子自动形成用于更高测序通量的串联体; 方法来创建一个原始核酸样品的多个拷贝(温度依赖的,多引发的,开放倍数复制),或产生含有多个原始核酸样品的多个拷贝的单个核酸分子(串联样品)以提高精度 并描述吞吐量; 以及改进修饰碱基调用的方法。
