A direct PCR approach is applied to our nanopore-based full-length 16S/18S/ITS sequencing, allowing the direct amplification of 16S/18S/ITS sequences from bacterial/archaeal/fungal/eukaryotic cell suspensions via PCR without DNA purification. This approach overcomes the limitations of the traditional culture-based bacterial identification, instead providing rapid and accurate microbial identification and diversity analysis.

The 16S rRNA gene is present in all archaea and bacteria, and consists of conserved and highly variable regions, making it ideal for the identification of prokaryotes. The 18S rRNA gene and internally transcribed spacer (ITS) are present in all eukaryotes and are suitable for eukaryotic identification and diversity analysis. Nanopore sequencing, a long-read sequencing technology, has obvious advantages in generating a more accurate profile of the microbiome than short-read sequencing technologies. It holds the promise of a microbiology revolution through generating real-time, long reads, with continuously increasing accuracy. Our nanopore-based 16S/18S/ITS sequencing provides rapid and accurate prokaryotic identification analysis with a relatively simple workflow and no need for DNA purification.
Nanopore-based 16S/18S/ITS sequencing is a novel molecular approach, with a more comprehensive and rapid process compared to the traditional culture-based bacterial identification, for the taxonomic characterization of microbial communities. In clinical microbiology, nanopore-based full-length 16S/18S/ITS sequencing can be used to diagnose bacterial infections and monitor outbreaks as acute infectious diseases remain one of the major causes of human diseases with high mortality. It can also be used to monitor and improve human health through gut or skin microbial diversity analysis. Nanopore-based 16S/18S/ITS sequencing can be applied to understand the role of microbes in agricultural, environmental, and health-related settings.
Our general bioinformatics analysis workflow includes data pre-treatment, taxonomic assignment, diversity analysis, evolutionary analysis, and custom analysis, which is flexible to your needs.
|Data pre-treatment||Quality control of the sequences, base calling|
|Taxonomic assignment||Operation taxonomic unit (OTU) clustering, identification of species|
|Diversity analysis||Classification and abundance analysis of single species and measurement of the difference in the bacterial community composition for different samples|
|Evolutionary analysis||Construction of phylogenetic trees, estimation of genetic distance|
|Custom analysis||Network analysis, correlation analysis, functional analysis, etc.|
