ChIP-on-chip Service

If you want to analyze transcriptional regulation from the DNA level in a more rapid and cost-effective manner and to map epigenetic changes in parallel at the whole genome level, we will provide you with the best ChIP-on-chip service in Creative BioMart to achieve your research goals.

What Is ChIP-on-chip?

ChIP-on-chip (also known as ChIP-chip) is a technique that combines chromatin immunoprecipitation (ChIP) with microarray technology, enabling us to rapidly determine the entire profile of DNA binding sites of a given protein, providing a genome-wide snapshot of transcriptional regulation mechanisms. This technique is very suitable for the comprehensive analysis of transcription factor binding sites, histone modification patterns, and nucleosome occupancy. The ChIP-on-chip can also be utilized to explore structural changes in the chromosome in any region of interest in a genome.

The general working principle of the ChIP-on-chip is as follows. After ChIP, DNA fragments are purified from the chromatin fraction recovered following chromatin immunoprecipitation (commonly referred to as the BOUND fraction). This fraction is enriched for the targeted histone modification or chromatin-related protein is fluorescently labeled. And then the DNA fragments are fluorescently labeled. DNA fragments from control input genomic DNA are also fluorescently labeled using a complementary fluorescent dye. Both sets of labeled DNA fragments are combined and hybridized to microarrays corresponding to the defined domain, locus or even whole genome. The enrichment region can be identified based on the ratio of signals from ChIP DNA and control DNA.

Features of ChIP-on-chip

  1. Histone modification, chromatin-related factors or modifying enzymes can be studied on a larger scale.
  2. The chromatin landscape can be mapped with high-confidence at a genome-wide level from a small biological sample amount.
  3. Allows for the identification of small differences in epigenome marks.
  4. Allows both the screening and downstream validation of target regions to be performed efficiently.
  5. Better spatial resolution and high-density tiling arrays enable the nucleosome-level ChIP-on-chip.
