A bit dense, but the important message is dead simple:
We got to cite the E = mc² paper!
Kidding :)
The important part is that combinations of isotopes unlock 100-1000x gains in protein measurement speed.
Here's how:

How to design 1000-plex mass tags using the differential mass defect
Multiplexing samples in mass spectrometry-based proteomics has long been accomplished by isotopologues of small molecules. These chemically-identical "mass tags" conjugate to peptides to encode sample...
