Figure 7. Relative fluorescence change of TO and G4-DNA complex (mole ratio of 3.5) at 530 nm upon the addition of (1) kanamycin, (2) terramycin hydrochloride, (3) streptomycin sulfate, (4) chloramphenicol, (5) chlortetracycline (6) ampicillin and (7) sulfadimethoxine (all at a final concentration of 20 μM) in 10 mM Tris–HCl buffer (pH 7.2) containing 10 mM NaCl.

Error bars represent the standard deviation in three individual experiments.
