Fig. 3. MALDI TOF mass spectra of a lysylendopeptidase digest of VLDL.

The ions of peptide (sequence 61–79 of apoC3, 2136.0 Da) and the corresponding glycopeptide containing Gal–GalNAc disaccharide (2501.2 Da) are indicated. Other signals are derived from apoC3 or other VLDL proteins. (a) linear TOF mass spectrum, (b) reflectron TOF mass spectrum.
