Next Generation Sequencing

Nov 12th, 2019, by Labtoo's team

High-throughput sequencing techniques have revolutionalized functional genomics. These thechniques are more and more popularized, allowing great progress in research.

NGS, the genomi revolution

What is it exactly?

The term NGS, also known as "high-throughput sequencing" refers to different sequencing technologies, amongst which are:

  • Illumina sequencing (most used)
  • Roche 454
  • Ion torrent
  • SOLiD
  • Helicos BioSciences

These technologies allow the sequencing of DNA or RNA much faster than the famous Sanger technique.

How does it work?

Three steps are shared for these techniques:

Bank preparation

Banks are created by random DNA fragmentation followed by linking to small specific sequences.

Amplification

The bank is amplified by clonal amplification methods and PCR.

Sequencing

The DNA is sequenced using different methods depending on the technology.

For what application?

There are many application possible, here are some :

Because it is an evolving techology, NGS can be used for sequencing non-referenced genomic sequences (de novo sequencing), for re-sequencing referenced genomes to find new genetic variants, for analysing transcipts (RNA-Seq), for identifying point mutations (SNPs), for insertin or deleting DNA fragments etc.
