Mapping of chromatin accessibility sites: ATAC seq
ATAC seq (Assay for transposase accessible chromatin) is an interesting methodology for identifying open chromatin regions, ascertaining positions with or without nucleosomes in regulatory regions, and analyzing the occupancy of transcription factors (TFs) in specific cell types. Thus, this application can generate fairly complete epigenomic profiles.
The principle of the technique consists in incubating the chromatin with Tn5 transposomes to simultaneously fragment and index the exposed DNA fragments (J Buenrostro et al. 2015). However, this simple and time-saving protocol must be carried out carefully in order not to modify the structure of the chromatin revealing sites to the transposomes.
