Figure 7From: Deglycosylation and label-free quantitative LC-MALDI MS applied to efficient serum biomarker discovery of lung cancer Bar chart representing the signal intensities of complement component C9 peptides detected from the tryptic digest of deglycosylated serum (filled bars) and untreated serum (open bars), n = 6. The numbers in parenthesis are amino acid numbers: 243-267 corresponds to 243FTPTETNKAEQCCEETASSISLHG267K and 22-44 corresponds to 22 QYTgTSYDPELTESSGSASHIDC44R, where "g" represents the site of O-linked glycan attachment. Error bars are one standard deviation.Back to article page
