MS spectra of tryptic peptides from spot A-9 (Annexin A2). (A) Peptide mass fingerprinting (PMF) of the trypsin-cleaved spot A-9. The sequence of Annexin A2 protein was represented by single-letter code for amino acids on the top right corner of the image and it was exhibited by red bold. Sequence coverage: 26%; (B) MS-MS sequence analysis of one of the parent ions, m/z value 2065.0024. The matched sequence was identified as RAEDGSVIDYELIDQDAR.
