From: Proteomic analysis of primary duck hepatocytes infected with duck hepatitis B virus
Representative mass spectra of annexin A2 analyzed by MALDI-TOF/TOF MS. The differentially expressed protein spot 49 was in-gel digested by trypsin, and peptide mixture was analyzed by MALDI-TOF/TOF Proteomics Analyzer. (A) MS spectrum with tryptic peptides of annexin A2, (B) MS/MS spectrum of the precursor ion with m/z 1111.67 marked in A for peptide QDIAFAYQR of annexin A2; fragments observed in the spectrum were underlined and assigned.
