Figure 7

Fluorescence emission spectra of hybridization complex with a series of different concentrations of HBV Target DNA added (a–j: 0 pM, 10 pM, 20 pM, 30 pM, 40 pM, 50 pM, 60 pM, 70 pM, 80 pM, and 90 pM). The inset shows the relationship between relative fluorescent intensity of after immunoreaction and the concentration of HBV Target DNA.
