Introduction to Chromatin Immunoprecipitation Sequencing (ChIP-seq)
Chromatin Immunoprecipitation Sequencing (ChIP-seq) provides genome-wide profiling of DNA targets for histone modification, transcription factors, and other 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.
Applications of Chromatin Immunoprecipitation Sequencing (ChIP-seq)
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
