Figure 3. CCD Images and 3D analysis of EL-CCD and LED-CCD detection of unquenched FITC-SNAP peptide.

Figure 3

The CCD images and the corresponding 3D imageJ analysis of the CCD emission images of nine concentrations of a 50% dilution series of the unquenched SNAP-25 peptide ranging from 0.019 nM to 5 nM and a control are shown for: (I) blue EL excitation exposure of 60 seconds, (II) blue EL excitation exposure of 300 s, (III) blue LED excitation exposure of 2 s and (IV) white LED excitation exposure of 3 s.
