  1. Relative differences in CCS (mean for n = 4 biological replicates) values were obtained by a parallel line model using a 2nd order polynomial fit. 1: The relative difference was obtained based on TIMS-MSI and LC-TIMS-MS data. Therefore, the latter was shifted by the mean relative deviation. All CCS values are presented in Ų.
