• ETD on Orbitrap FTMS produced 162 identified unique backbone cleavages sites on ~150 kDa intact protein (IgG) on the LC timescale. • Sequence coverage obtained by ETD is generally higher than the one obtained by slow-heating activation methods and, importantly, provides valuable information on the variable domains. • ETD fragmentation patterns of IgGs derived from different organisms (i. e., with significant differences in sequence-structure) show relevant differences in the number and abundances of product ions, especially in the 200-1200 m/z region. • Further improvement in S/N is required for identification of PTMs and increased sequence coverage.
