Representative MALDI-TOF peptide mass fingerprint spectrum of spot b. After trypsin digestion, the resulting peptides were analysed by MALDI-MS and MS/MS analyses. Peptide mass fingerprints (PMFs) data were searched against the database of SwissProt by BioTools 3.0 software. The protein with molecular mass of approximately 42 kDa was identified as haptoglobin (Hp) by the sequence analysis.
