Proteomics

​

The field of MS-based Quantitative Proteomics has matured to a point that it is now routine to undergo quantitative, comparative investigations into the proteome to better understand disease and to search for potential protein biomarkers. Although some quantitative measurements are made without the use of stable isotopes, the use of labelled samples, in conjunction with mass spectrometry, generally increases the accuracy of the quantitative results; saves time by requiring fewer experimental replicates; and requires less sophisticated and thus less expensive instrumentation.
