I'm just putting these here so that they'll pop up in Google image searches in the future.
Of course, this should go without saying, but just to be clear: iTRAQ and TMT are the properties of Proteome Sciences and are trademarked to ABI(TM,R) and Thermo Fisher Scientific (TM,R), respectively.
In no particular order here are these poorly drawn images. Go Google Image Crawler go.
EDIT 3/22/18: TOTALLY WORKED!! Only image on the front page of Google Images with anything behind the decimal place.
