The automatic-targeted analysis of the complement C4B-peptide (NGFKSHALQLNNR) at time 0, 1 and 72 h incubation at room temperature. a, The normality of the log10 transformed intensity data as assessed by quantile plot; b the mean and standard deviation of the targeted precursor intensity value (different letters indicate a significant difference by the Tukey–Kramer Honestly Significant Difference Test); c the histogram showing the frequency of observing peptides in each log10 intensity bin. Automatic targeted sampling showed a 100-fold increase in frequency and about a 10-fold to 100-fold increase in C4B-peptide intensity with incubation at room temperature
