The power of our ECD technology comes from the ability to either combine or switch between fragmentation modes.
Here we illustrate how CID fragmentation can be turned off and on quickly to provide sequence-revealing complementary fragmentation patterns. These complementary pairs have been called Golden Pairs. The ability of our technology to switch fragmentation modes opens many new possibilties for improving the accuracy of protein and peptide identification as well as quantification of fragile post-translational modifications.
