A simple osmometer with nuclear filters (polymer films with pores of a preset diameter) were used to measure the osmotic pressure of Col E1 plasmid DNA solutions in the concentration range of 1-4 mg/ml DNA. Linear and open circular DNA forms proved to have the same osmotic pressure within the experimental accuracy. The results of the measurements were used(More)
Binding constants have been measured for the interaction of the protein HMG1 with native DNA, denatured DNA and a number of polynucleotides at near-physiological ionic strengths, using gel filtration and thermal denaturation. The interaction of HMG1 with DNA is shown to be noncooperative and reversible. Nucleic acids form the following series in order of(More)
