Table 2.
Oxidative modifications of CYGB. A list of the number of oxidized peptide fragments before and after plasma treatment. The number of Peptide Spectrum Matches (PSM) is the total number of identified peptide spectra matched for the protein. Samples were measured with Ion trap LC-MS/MS and spectra were analyzed with Mascot and Sequest algorithms.
