  • Publication number: 20180282800
    Abstract: Improved single molecule sequencing methods, compositions, and devices, are provided. In a first aspect, the present invention provides a multi-pass method of sequencing a target sequence using nanopore sequencing, the method comprising: i) providing a non-naturally occurring concatemer nucleic acid molecule comprising a plurality of copies of the target sequence; ii) nanopore sequencing at least three copies of the target sequence in the concatemer, thereby obtaining a multi-pass sequence dataset, wherein the multi-pass sequence dataset comprises target sequence datasets for the at least three copies of the target sequence; and iii) using the multi-pass sequence dataset to determine the target sequence.

  • Publication number: 20140017683
    Abstract: A method for analyzing a genome of a single cell is provided, and a kit is also provided. The method for analyzing the genome of the single cell may comprise separating and lysing the single cell to obtain a whole-genome DNA of the cell; subjecting the whole-genome DNA to a whole-genome amplification to obtain a whole-genome amplification product; performing a PCR amplification using the whole-genome amplification product as template and using housekeeping-gene-specific primers to detect the housekeeping gene of the whole-genome amplification product; and determining whether the whole genome amplification product meets a requirement for sequencing based on the detection result, wherein a uniform distribution of the amplification product in each chromosome is an indication of the amplification product meeting the requirement for sequencing.
