Web25 jul. 2024 · Abstract. DNase I hypersensitive sites (DHSs) are genomic regions that exhibit hypersensitivity to DNase I cleavage. DHSs appear to be an essential feature of “open chromatin” structure in eukaryotes. Most of regulatory elements and the majority of transcription factor-binding sites are associated with open chromatin marked by DHSs. WebYou can use water to reconstitute your DNAse by adding 2ml (H2O) to the powder vial to have 2000U/2ml (=1U/µl). Keep your DNAse suspension in aliquots at -20°C to preserve its activity. Cite...
