ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing) is a technique used in molecular biology to assess genome-wide chromatin accessibility. [1] In 2013, the technique was first described as an alternative advanced method for MNase-seq, FAIRE-Seq and DNase-Seq. [1]
Chromosome conformation capture techniques (often abbreviated to 3C technologies or 3C-based methods [1]) are a set of molecular biology methods used to analyze the spatial organization of chromatin in a cell. These methods quantify the number of interactions between genomic loci that are nearby in 3-D space, but may be separated by many ...
Of interest in the context of Hi-C, and all 3C-based methods, is the ability of formaldehyde to capture cis chromosomal interactions between distal segments of chromatin. [ 1 ] [ 4 ] [ 15 ] [ 16 ] It does so by forming covalent links between spatially adjacent chromatin segments.
Chromatin Immunoprecipitation sequencing, also known as ChIP-seq, is an experimental technique used to identify transcription factor binding events throughout an entire genome. Knowing how the proteins in the human body interact with DNA to regulate gene expression is a key component of our knowledge of human diseases and biological processes.
ChIP-sequencing, also known as ChIP-seq, is a method used to analyze protein interactions with DNA. ChIP-seq combines chromatin immunoprecipitation (ChIP) with massively parallel DNA sequencing to identify the binding sites of DNA-associated proteins. It can be used to map global binding sites precisely for any protein of interest.
ChIP-seq (Chromatin immunoprecipitation sequencing) is recognized as the vastly utilized chromatin identification method it has been using the antibodies that actively selected, identify and combine with proteins including "histones, histone restructuring, transaction factors and cofactors".
The ChIA-PET method combines ChIP-based methods, [2] and Chromosome conformation capture (3C) based methods, [3] to extend the capabilities of both approaches. ChIP-Sequencing (ChIP-Seq) is a popular method used to identify transciption factor binding sites (TFBS) while 3C has been used to identify long-range chromatin interactions.
While MNase-seq is primarily used to sequence regions of DNA bound by histones or other chromatin-bound proteins, [2] the other three are commonly used for: mapping Deoxyribonuclease I hypersensitive sites (DHSs), [6] sequencing the DNA unbound by chromatin proteins, [7] or sequencing regions of loosely packaged chromatin through transposition ...
