Figure 3.
Comparison of the low m/z region of the native top-down ECD spectra of intact anti-CD20 IgA1 spectrum reconstructed from charge-deconvoluted spectra corresponding to fragment charge states ranging from 1+ to 13+ (top spectra), with the unprocessed fragment ion spectrum (bottom spectrum). The most represented charge states are color annotated. Cross-correlation analysis, using a 100 m/z sliding window in steps of 10 m/z, yields an average high score of 0.964.
