Figure 4. Degradation of the 33-mer in human whole saliva (WS).

The 33-mer was added to a final concentration of 250 µg/ml to WS collected from eight individual subjects. In each of the saliva samples, the degradation of the 33-mer was monitored. The average peak area and standard deviation of the 33-mer incubated for 0 h, 2 h, 5 h, 8 h and 24 h in the eight WS samples are shown. Control: 33-mer only, incubated in saliva ion buffer for the same time intervals.
