Fig. 6From: Enhanced differentiation of isomeric RNA modifications by reducing the size of ions in ion mobility mass spectrometric measurementsCalibration graphs of (a) m6A and (b) m3C using the SRI method. The MS/MS data (solid line) of a specific post-IM CID fragment ion or the IM data (dotted line) of corresponding methylated nucleobase are plotted against the concentration of methylated ribonucleoside in standard dilution. The error bars represent one standard deviation (n = 3)Back to article page
