Introduction to our Nanopore sequencing

The nanopore sequencing technology detects the real-time electric current of single-stranded DNA (ssDNA) as it passes through a small protein channel, or the nanopore. The electric current data is then converted into a corresponding sequence. This technology relies on the physicochemical properties of ssDNA rather than enzymatic reactions. The sequencing speed has been greatly improved compared with next-generation sequencing systems. MinION is the only portable, real-time device for DNA and RNA sequencing on the market. The average reading length of nanopore technology can reach tens to hundreds of Kb, and the longest reading length can reach 2 Mb. Highly contiguous genome assembly can be generated for many large and complex organisms that are deemed inaccessible to NGS methods. As a result, nanopore sequencing could provide a more complete view of the genetic content and variation.

In addition to improving read length and sequencing speed, nanopore sequencing could reduce or eliminate sequencing bias caused by PCR amplification. The anopore sequencing has significantly improved de novo genome assemblies, detection of genomic structural variant, and transcriptome studies. The real-time streaming of sequence data allows for rapid insight into samples, on-demand sequencing, and dynamic workflows. We are dedicated to offering diverse microbial genomics services in the following four aspects: genome analysis, 16S rRNA sequencing, epigenomics, and transcriptomics. Problems such as complex genome assembly, and detection of structural variations can all be solved with the nanopore sequencing.
