Identification of syntenin-1 (SDCB-1) peptides in odontoclast-derived exosomes by mass spectrometry (MS). A, B: Extracted ion chromatogram (XIC) for m/z 603.81 and MS spectra at 82.9 min from LC-MS of bone-derived exosome digest; C, D: respective XIC and MS spectra from dentin-derived sample. Note that respective peak for syntenin-1 in panel B (bone) is lower than a threshold for MS/MS acquisition (300 counts per second). E: MS/MS spectra of 603.816 peak with assignment of selected y-ions
