Comparison of mean preprocessed ion intensities and 95% confidence intervals between replicate experiments of WT flies for the fourteen isotope distributions identified by MALDI-TOF/TOF MS/MS to be neuropeptides. Linear regression between the mean values of the fourteen isotope distributions gave an R² = 0.969. The dashed red line shows where mean intensity values should be had they been identical between the two repeat experiments. The dashed purple and blue lines show where the log₂ ratio between two conditions would be 1 or 2, respectively. 95% confidence intervals in either experiment generally were within 1 log₂ ratio.
