From: Pox proteomics: mass spectrometry analysis and identification of Vaccinia virion proteins
Mass analysis of a distinct peptide from the L3L protein using Method 4 (LC-ESI-Q-TOF MS). The core-enriched fraction of the virion was subjected to trypsin digestion, and analyzed by the LC-ESI-Q-TOF mass spectrometer. The full scan mass spectrum displays a peak at m/z 844.5 (inset), and corresponding tandem mass spectrum identifies a peptide of the L3L protein. Four internal fragments were also identified for the L3L peptide including: PL, GFP, PLL, and GFPL.
