[…] ms; isolation window=1.6 m/z; nce=27, 30; dynamic exclusion=15 seconds). ms/ms spectra were matched to peptide sequences using mascot (version 2.2.1) after conversion of raw data to .mgf using multiplierz scripts . search parameters specified trypsin digestion with up to two missed cleavages, as well as variable oxidation of methionine and carbamidomethylation of cysteine residues. […]

[…] of cysteine (carbamidomethylation) and peptide n-termini and lysine (4-plex itraq) as well as variable modification of serine, threonine, tyrosine (phosphorylation) and methionine (oxidation). multiplierz scripts were used to filter results to a 1% fdr, remove hits with mass deviations >50 ppm, and extract itraq reporter ion intensities. ratios were corrected for source protein […]
