Figure 7: Quantitative evaluation of the gliadin spots.

(a) Plot of fluorescence of the gliadins spotted by the PC, as a function of the dilution factor and corresponding linearity curve. (b) Mean fluorescence profiles of the PC-spotted gliadins for six dilutions and corresponding scanner image where the dilution grows from top to bottom, scale bar, 300 μm. Each datum in a is the mean of 10 replicates and the error bars represent the s.d. from the averages.
