Chromatin Immunoprecipitation Sequencing (ChIP-seq)

Introduction to ChIP-seq

Chromatin Immunoprecipitation Sequencing (ChIP-seq) provides genome-wide profiling of DNA targets for histone modification, transcription factors, and aother DNA-associated proteins. It combines the selectivity of chromatin immuno-precipitation (ChIP) to recover specific protein-DNA complexes, with the power of next-generation sequencing (NGS) to achieve high-throughput sequencing of the recovered DNA.

As protein-DNA complexes are recovered from living cells, binding sites can be compared in different cell types and tissues, or under different conditions. At Novogene, we offer high-quality sequencing and comprehensive bioinformatics solutions for your ChIP-seq projects.

How does ChIP-seq apply?

ChIP-seq provides regulatory solutions and meets customized research needs, such as:

  • Understanding how transcription factors regulate genes by profiling a genome-wide binding site and analyzing motif.
  • Outlining histone modification patterns associated with experimental treatment or sample conditions.
  • Investigating the relationships between epigenetic profiles and transcriptional regulations through joint analysis.
  • Accommodating to multiple immunoprecipitated DNAs using various methods, including ChIP, Cut&Tag, etc..

Benefits of Novogene ChIP-seq

  • The output data is stable and reliable, with the guaranteed data quality of the sequencing score Q30≥ 80%.
  • Expert bioinformatics analysis utilizes industry-standard MACS2 software and programs with the latest version to get motif prediction, peak annotation, functional analysis, and data visualization.
  • Associated analysis is provided to explore correlations between ChIP-seq and gene expression.
