Electron-transfer dissociation (ETD) is a method of fragmenting multiply-charged gaseous macromolecules in a mass spectrometer between the stages of tandem mass spectrometry (MS/MS). Similar to electron-capture dissociation, ETD induces fragmentation of large, multiply-charged cations by transferring electrons to them. ETD is used extensively with polymers and biological molecules suc… WebFunctional regions of the TMTpro reagent’s chemical structure, including MS/MS sites of fragmentation by HCD. *Note: TMTpro and TMT 6,10 & 11 plex reagents are mutually exclusive and cannot be mixed and matched. …
