Figure 5.

G-quadruplex formation in 16 long dsDNAs derived from human genome examined by native gel electrophoresis. DNAs in 150 mM K⁺, 40% (w/v) PEG 200 solution were subjected to heat denaturation/renaturation (right lane) or were not heat-treated (left lane) before electrophoresis. The gel was stained with ethidium bromide (EB). The drawing at the right side shows schematic illustration of the structure associated with the corresponding DNA band.
