Figure SI 1: Analytical performance of the SRM assays developed for targeted (phospho)proteomics. The boxes represent the interquartile range, with the median shown as a line within the box and whiskers extending to the minimum and maximum values (A) Sensitivity and Linearity (n=3): The left panel displays the distribution of limits of quantification (LOQ) for all target (phospho)peptides. The right panel shows the distribution of correlation coefficients (R²) from the calibration curves for all targeted (phospho)peptides. (B) Reproducibility: Box plots show the distribution of coefficient of variation (%CV) for all measured (phospho)peptides across different concentration levels and replicates (n=5) measured over 3 consecutive days.
