Superhelix dimensions of a 1868 base pair plasmid determined by scanning force microscopy in air and in aqueous solution.
We have used scanning force microscopy (SFM) to study the conformation of a 1868 base pair plasmid (p1868) in its open circular form and at a superhelical density of sigma= -0.034. The samples were deposited on a mica surface in the presence of MgCl2. DNA images were obtained both in air and in aque...
