Fig. 8.5. PSD spectra of C-terminal AspN peptides derived from the F2-polypeptides of (A) the VRI
82-6409 and (B) V 4 isolates of NDV. Detailed descriptions of the ions observed are presented in Table
8.2 and summarized above the respective spectra. Only representative ions are indicated on the spectra. These spectra were collected using continuous extraction and a digitization rate of 250 MHz. These
spectra were adapted with permission from (Lopaticki et al. 1998; Copyright, John Wiley + Sons)
