Gut Microbiota Nanopore Long-Read Sequencing


Gut Microbiota Nanopore Long-Read Sequencing

The introduction of next-generation sequencing has revolutionized molecular biology, and high-throughput sequencing systems are now commonly used in phylogenomic and metagenomic research. Though next-generation sequencing restricts the read-length of the process that ensures accuracy and fidelity, it does so while analyzing a significant number of amplified identical DNA strands. Because eukaryotic genomes include many repetitive areas, long DNA molecules must be split up into small parts, which could be a significant constraint of eukaryotic DNA sequencing. Third-generation sequencing techniques can sequence much longer reads than next-generation sequencing because they sequence single molecules instantly, resulting in a reformation in high-quality genome sequencing, enabling for unbiased, more precise classification and even higher taxonomic resolution than second-generation sequencing methodologies for gut microbiota research. The third generation of sequencing has surmounted the sophistication of short-read second-generation sequencing information assembly and the incapability to efficiently fix repeat sequences or huge genomic rearrangements; they all produce very long reads (1–100kb), which is unique from next-generation sequencing.

Our Advantages

  • The mappable length (> 2 Mb) is slightly longer
  • Since the nanopores can sequence numerous molecules, ONT MinION has a very large throughput
  • The expense of generating ONT data is lesser. Because sequencing costs are a significant barrier to TGS application, ONT's relatively high throughput and low price make it interesting for a variety of applications.

Workflow and Bioinformatics Analysis

Workflow of Our Nanopore Long Read Sequencing Service
Bioinformatics AnalysisDetails
Remove redundantErase genetic redundancy, which occurs when two or more genes conduct the same purpose and inactivation of one of these genes has little or no effect on the biological phenotype.
Gene Functional AnalysisRecognising any functional element along a genome's DNA sequence, but with a focus on genes at first.
SNP CallingFiguring bases that vary from the reference genome in genetic data, usually with a related confidence score or statistical evidence metric.
Gene Expression AnalysisDifferential expression assessment and quantification of gene/transcript expression stages
Functional Enrichment AnalysisCategorizing gene or protein classes that are over-represented in a large number of genes or proteins and may be linked to disease phenotypes.
PPIsProtein-protein interactions are detected and identified.

Creative Proteomics is dedicated to providing the highest level of service to facilitate gut microbiota research.
