The selective extraction of endogenous serum peptides has been a challenge due to the high abundant proteins present in serum. Here a simple on-line extraction of peptides from human serum using strong cation-exchange diol silica restricted-access materials (SCX-RAM) coupled with two-dimensional RP–RP liquid chromatography mass spectrometry was developed. The operation of the on-line extraction system...
Peptides in urine are excreted by kidney from the blood and tissues, which are composed of a large amount of hormones, cytokines, regulatory factors and the metabolized fragments of proteins. The peptide distribution in urine will reflect the physiological and pathophysiological processes in body. In past, limited information was reported about the composition of the peptides in urine. One possible...
