Electron Transfer Dissociation (ETD)
Catalog number: IQLAAEGABBFACCMAFJ
Achieve better analysis of proteins and their post-translational modifications (PTMs) with the Thermo Scientific™ Electron Transfer Dissociation (ETD) option. Unlike CID, which cleaves weakly bound modifications off the peptide backbone, ETD induces fragmentation along the peptide backbone in a sequence-independent manner, leaving labile modifications linked to the peptide chain. This greatly simplifies identification of modification sites. ETD produces primarily c- and z-type fragment ions that complement the b- and y-type ions produced by CID, increasing sequence coverage and protein IDs.
