Keller, W. (1975) Determination of Number of Superhelical Turns in Simian Virus 40 DNA by Gel-Electrophoresis. Proceedings of the National Academy of Sciences of the United States of America, 72 (12). pp. 4876-4880.
Abstract
Closed-circular, superhelical DNA from simian virus 40 (SV40 DNA I) was treated with an excess of DNA-relaxing enzyme in the presence of increasing amounts of ethidium bromide (EtdBr). After removal of the ethidium, each sample consisted of a group of close-circular DNA molecules differing in their number of superhelical turns (tau) around a mean value of tau in a Gaussian-like distribution.
