Chimeric spectra

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. WebMay 3, 2024 · The impact of using chimeric spectra differs depending on the variables and the colours involved in the chimeric measurement (Fig. 3). 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%). ...
