WebMay 15, 1993 · DNase I hypersensitivity assay. K562 cells were maintained in RPMI containing 10% fetal calf serum (FCS). Cells were pelleted, washed with phosphate-buffered saline (PBS), and resuspended in ice-cold 10 mmol/L Tris, pH 7.8,4 mmol/L MgCl 2,1 mmol/L EDTA, 0.3% NP-40. In genetics, DNase I hypersensitive sites (DHSs) are regions of chromatin that are sensitive to cleavage by the DNase I enzyme. In these specific regions of the genome, chromatin has lost its condensed structure, exposing the DNA and making it accessible. This raises the availability of DNA to degradation by … See more The ENCODE project proposes to map all of the DHSs in the human genome with the intention of cataloging human regulatory DNA. DHSs mark transcriptionally active regions of the genome, … See more The study of DHS profiles combined with other techniques allows analysis of regulatory DNA in humans: • Transcription factor: Using the ChIP-Seq technique, the … See more • ENCODE Project: Regulatory Elements DB • Plant DHSs : PlantDHS See more
