This larger number of molecules and the associated larger dynamic range have major implications in the application of proteomics technologies. We examine these implications for both liquid chromatography-tandem mass-spectrometry (LC-MS/MS) and single-molecule counting and provide estimates on how many molecules are routinely measured in proteomics experiments by LC-MS/MS. We review strategies that have been helpful for counting billions of protein molecules by LC-MS/MS and suggest that these strategies can benefit single-molecule methods, especially in mitigating the challenges of the wide dynamic range of the proteome. We also examine the theoretical possibilities for scaling up single-molecule and mass-spectrometry proteomics approaches to quantifying the billions of protein molecules that make up the proteomes of our cells.Thu Mar 30 00:00:00 GMT+01:00 2023PXD035637960636899164
