Abstract
Isobaric mass spectrometry tags (e.g., TMT) are susceptible to ratio compression, which arises from the co-isolation and co-fragmentation of interfering species that also contribute to the final reporter ion ratios. Additional stages of ion activation/transformation (e.g., MSn and PTR) have been shown to decrease ratio compression. Embodiments of the present invention include a mass spectrometry cleavable moiety on the isobaric mass tags. The cleavable moiety allows for a predictable mass loss, and results in an improved tag reporter ion purity.
