*1 Detected as a doubly charged ion on BLOTCHIP-MS peptide profiling.
*2 Although only partial MS/MS spectra was obtained, mass of the whole chain was identical to the calculated value.
Characteristics of the 14 identified peptides are shown. MALDI-TOF/TOF and LC-MS/MS peptide sequencing analyses were performed using partially purified serum peptides after reverse-phase chromatography. Some of the identified peptides were modified (see details in manuscript).
