Understanding the genetic code

NGS technology enables massively parallel DNA analysis for a deeper understanding of biology

DNA Sequencing

Illumina next-generation sequencing (NGS) technology uses clonal amplification and sequencing by synthesis (SBS) chemistry to enable rapid, accurate sequencing. The process simultaneously identifies DNA bases while incorporating them into a nucleic acid chain. Each base emits a unique fluorescent signal as it is added to the growing strand, which is used to determine the order of the DNA sequence.

NGS technology can be used to sequence the DNA from any organism, providing valuable information in response to almost any biological question. A highly scalable technology, DNA sequencing can be applied to small, targeted regions or the entire genome through a variety of methods, enabling researchers to investigate and better understand health and disease.

Introduction to DNA Sequencing
  • Sequences large stretches of DNA in a massively parallel fashion, offering advantages in throughput and scale compared to capillary electrophoresis–based Sanger sequencing
  • Provides high resolution to obtain a base-by-base view of a gene, exome, or genome
  • Delivers quantitative measurements based on signal intensity
  • Detects virtually all types of genomic alterations, including single nucleotide variants, insertions and deletions, copy number changes, and chromosomal aberrations
  • Offers high throughput and flexibility to scale studies and sequence multiple samples simultaneously
