Summary of Technical Depth of Orbitrap-, QTOF-, and Triple-TOF-based Studies. A protein only needs to be identified in one sample to contribute to the total number of unique proteins (indicated as “total” below), thus the total is typically larger in studies with greater sample numbers. An iTRAQ or TMT set is a pool of samples that are run on the LC-MS/MS concurrently. Because the samples in a set are all analyzed simultaneously, a set's contribution to the total number of unique proteins is similar to that of a single sample
