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.

Whole-Genome Sequencing

Whole-genome sequencing is a comprehensive method for analyzing entire genomes. Rapidly dropping costs and the ability to produce large volumes of data with today’s sequencers make this a powerful research tool.

Targeted Resequencing

With targeted resequencing, a subset of genes or regions of the genome are isolated and sequenced, allowing scientists to focus time, expenses, and analysis on specific areas of interest.

Exome Sequencing

This DNA sequencing method involves analyzing the protein-coding regions of the genome to uncover genetic influences on disease and population health.

Target Enrichment

Target enrichment captures genomic regions of interest through hybridization and allows researchers to reliably sequence large numbers of genes (typically > 50 genes) at once.

Methylation Sequencing

Leveraging the power of NGS, both genome-wide analysis and targeted approaches can provide researchers with insight into DNA methylation patterns at a single nucleotide level.

ChIP Sequencing

By combining chromatin immunoprecipitation (ChIP) assays and sequencing, ChIP-Seq is a powerful method to identify genome-wide DNA binding sites for transcription factors and other proteins.

Our versatile library prep portfolio allows you to examine small, targeted regions or the entire genome. We've innovated in PCR-free and on-bead fragmentation technology, offering time savings, flexibility, and increased sequencing data performance.
