Isolation of Chromatin DNA Tightly Bound to the Nuclear Envelope of HeLa Cells

Isolation of Chromatin DNA Tightly Bound to the Nuclear Envelope of HeLa Cells Recent discovery of the role of nuclear pores in transcription, predicted by our early DNA-membrane complex (DMC) model, makes membrane-bound DNA (MBD) isolation from the cell nucleus and analysis of the MBD actual. The method of MBD isolation proposed by us retains DMC integrity during isolation. We used HeLa cells for DMC extraction. Changing the ionic composition of the isolation medium and replacing DNase I, used commonly for chromatin destruction, with a set of restriction enzymes allowed us to isolate the MBD. Treatment of a nuclear membrane with proteinase K and ultrasound has been used to increase the yield of MBD. Electron microscopic analysis of the purified fraction of isolated DMC supports our previous model of nuclear envelope lipid–chromatin interaction in the nuclear pore assembly. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Journal of Membrane Biology Springer Journals
