FIGURE 6.
A two-dimensional denaturing gel showing the products of ligating DAE-42. The gel has been divided into two portions for clarity. The smaller (primarily linear) molecules are shown in a lower panel, and the rest in an upper panel. Linear products are indicated by the designation Ln, where the number n indicates the number of fundamental (42-mer) repeats are contained in the molecule. Single circles are indicated by the notation C′n, and cyclic catenated products are indicated as Cn. Note how successive species form arcs on the gel.
