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 … orcinus technologies inc

"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 … Webof the peptides in such mixed spectra, but rarely can such search engines identify all of the peptides. The CHIMERYS intelligent search algorithm helps address this issue by identifying significantly more peptides in chimeric spectra, dramatically increasing the number of peptide identifications in complex proteomics LC-MS/MS runs. orcinus orca是什么
