Web14. jan 2015 · Top-down is not readily applicable to heavier polyubiquitins because their mass is too high for the capabilities of current mass spectrometers. The middle-out approach reduces the mass by trimming the branches, and allows the trunk or backbone with sequential branch points to be recovered for easier analysis. Web1. jan 2024 · Top-down mass spectrometry (TDMS) differs from the traditional bottom-up approach in that proteins are analyzed directly, rather than enzymatically digested prior to analysis. While bottom-up tends to be faster and more readily implemented, top-down has improved selectivity, enabling simultaneous characterization of dynamic and hard-to …
