Took nuclei from cells and treated with Dnase 1 and trims accessible chromatin - the logic here is that regions that would be accessible to DNase1 would also be accessible to a transcription factor. After DNase treatment DNA is treated with EcoR1 to produce fragments. honk job paymentWebThe increased sensitivity to DNase I digestion is not directly related to the transcriptional process since the enzyme also preferentially digests gene sequences which have been but are no longer transcribed (Weintraub and Groudine, 1976; Miller et al., 1978), and also digests genes that are transcribed at different rates with equal sensitivity ... hon k jones

"WebA powerful research tool for DNA manipulations, DNase I is used in a range of molecular biology applications. Some of its uses include: 1. Degradation of contaminating DNA after RNA isolation, 2. "Clean-up" of RNA prior to RT-PCR and after in vitro transcription, 3. Identification of protein binding sequences on DNA (DNase I footprinting), 4. " - Dnase i hypersensitivity assay

Dnase i hypersensitivity assay

WebDNase I is a protein that can cut DNA and this cutting process works better when the template DNA is accessible, meaning that highly accessible regions are more sensitive to DNase I activity. The behaviour of the genome in the DNase I hypersensitivity assay can therefore be used to learn indirectly about its structure, from which researchers ... WebPrinciple. The DNAse I Activity Assay Kit allows for quantitative evaluation of DNAse I activity of purified enzymes and their inhibitors, as well as comparative examination of DNAse I activity in biological samples. Enzyme activity is detected upon cleavage of a DNA Probe, which yields a fluorescent DNA product measured at λ Ex = 651nm/λ Em ...
