Precise analysis of DNA–protein binding sequences

Combining chromatin immunoprecipitation with NGS for genome-wide surveys of gene regulation

Chromatin Immunoprecipitation Sequencing (ChIP-Seq)

By combining chromatin immunoprecipitation (ChIP) assays with sequencing, ChIP sequencing (ChIP-Seq) is a powerful method for identifying genome-wide DNA binding sites for transcription factors and other proteins. Following ChIP protocols, DNA-bound protein is immunoprecipitated using a specific antibody. The bound DNA is then coprecipitated, purified, and sequenced.

The application of next-generation sequencing (NGS) to ChIP has revealed insights into gene regulation events that play a role in various diseases and biological pathways, such as development and cancer progression. ChIP-Seq enables thorough examination of the interactions between proteins and nucleic acids on a genome-wide scale.

  • Captures DNA targets for transcription factors or histone modifications across the entire genome of any organism
  • Defines transcription factor binding sites
  • Reveals gene regulatory networks in combination with RNA sequencing and methylation analysis
  • Offers compatibility with various input DNA samples
Advantages of ChIP-Seq

ChIP-Seq identifies the binding sites of DNA-associated proteins and can be used to map global binding sites for a given protein. Unlike arrays and other approaches used to investigate the epigenome, which are inherently biased because they require probes derived from known sequences, ChIP-Seq does not require prior knowledge. ChIP-Seq delivers genome-wide profiling with massively parallel sequencing, generating millions of counts across multiple samples for cost-effective, precise analysis.

Unbiased Investigation of Epigenetic Patterns

Illumina sequencing by synthesis (SBS) chemistry is the most widely adopted NGS technology, generating approximately 90% of global sequencing data.*

In addition to industry-leading data quality, Illumina offers integrated workflows that simplify sequencing, from library preparation to data analysis.
