LTQ-Orbitrap analysis of HAND L-PGDS tryptic peptides: TMLLQPAGSLGSYSYR and TMLLQPAGSLGSYNO2SYR. The base peak ion chromatograms of the MS analysis of the tryptic digestion of HAND L-PGDS are presented in Panel A. The single ion chromatograms at m/z 872.48 and m/z 894.94 represent the detection of the [M+2H]+2 ion of the non-nitrated and nitrated HAND L-PGDS peptide, respectively. The tandem MS spectra of m/z 872.48 and m/z 894.94 are in Panel B
