Figure 4. Overlap of validated 3NT peptides identified by the QSTAR Elite and LTQ Velos.

Figure 4

Venn diagram of the overlap of all validated 3NT (A) and multiply 3NT modified (B) peptides identified by the QSTAR Elite and LTQ Velos. Distinct peptides were defined as differences in the site of nitration, missed cleavages, and methionine oxidation state
