Isolation and Characterization of Supercoiled Circular Deoxyribonucleic Acid from Beta-Hemolytic Strains of Escherichia coli
Covalently closed circular deoxyribonucleic acid (DNA) molecules were isolated by cesium chloride centrifugation in the presence of ethidium bromide from a naturally occurring beta-hemolytic Escherichia coli strain (SC52). The open circular forms have contour lengths of 2.25 ± 0.1 μm, 24.0 ± 0.3 μm,...
