Various experimental techniques have been developed for genome-wide mapping of epigenetic information, [4] the most widely used being ChIP-on-chip, ChIP-seq and bisulfite sequencing. All of these methods generate large amounts of data and require efficient ways of data processing and quality control by bioinformatic methods.
Such rich epigenomic mapping, however, representing different ages, tissue types, and disease states, would yield valuable information on the normal function of epigenetic marks as well as the mechanisms leading to aging and disease. Direct benefits of epigenomic mapping include probable advances in cloning technology. It is believed that ...
As EPIC-seq studies epigenetic markers to infer gene expression, one can study epigenetic sequencing methods like ChIP-seq, [30] ATAC-seq, [31] MeDIP-seq, [32] and Bisulfite-Free DNA Methylation sequencing [33] in combination with methods for profiling RNA expression such as RNA-seq [34] and scRNA-seq.
Applications of ATAC-Seq. ATAC-Seq analysis is used to investigate a number of chromatin-accessibility signatures. The most common use is nucleosome mapping experiments, [3] but it can be applied to mapping transcription factor binding sites, [13] adapted to map DNA methylation sites, [14] or combined with sequencing techniques.
Epigenomics is the study of the complete set of epigenetic modifications on the genetic material of a cell, known as the epigenome.The field is analogous to genomics and proteomics, which are the study of the genome and proteome of a cell.
The Epigenomics database of the National Center for Biotechnology Information (NCBI) at the National Institutes of Health (NIH) was launched in June 2010 as a means to collect maps of epigenetic modifications and their occurrence across the human genome. [2]

Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between proteins and DNA in the cell. It aims to determine whether specific proteins are associated with specific genomic regions, such as transcription factors on promoters or other DNA binding sites , and possibly ...
