Characterization of the G-quadruplex structures: (A) Circular dichroism oligonucleotides in phosphate-buffered saline (PBS) buffer pH 7.4. (B) 20% Polyacrylamide gel electrophoresis analysis of the structures formed upon incubation of the different DNA sequences in TBE buffer supplemented with 100 mMKCl. Lanes (1) dye; (2) T8; (3) T12; (4) TG4T; (5) FdU5-TG4T; (6) TG6T; (7) FdU5-TG6T; (8) FdU10-TG6T; (9) empty lane; (10) Fam-T8; (11) Fam-T12; (12) Fam-FdU5-T8; (13) Fam-FdU5-TG4T; (14) Fam-FdU5-TG6T. The gel was stained with Stains-All.
