Identification of Chimera Spectra—State of the Art. Identification of the chimera spectra stemming from co-fragmenting approximately isobaric sequences can be achieved using a high quality, high mass resolution MS analysis of the precursor ions prior to fragmentation, which forms the basis of multiplexed tandem MS [].On lower resolution …

When a UV-blue and a black patch are involved in a chimeric spectrum, the shape of the spectrum (e.g. peak location) is generally conserved but luminance values drop dramatically (−40 ± 3%). ...
WebJun 18, 2024 · "The parent mass is exactly the same and they have very similar [LC] retention times, so you often get chimeric spectra of both phosphorylation site isomers," Tenzer said. "We've seen that a number of these [isobaric] phosphopeptides are actually pretty nicely separated in the gas phase by ion mobility," he said. "That's a huge benefit … WebJul 1, 2016 · Features can also be used to perform untargeted analysis of data-independent acquisition (DIA) experiments. 13 Lastly, recent work has shown that feature information can increase the identification rates of chimeric MS/MS spectra, providing a cheap possibility to increase the number of identified spectra and the quality of the data analysis. 14
