Mass analysis of a distinct peptide from the L1R protein using Method 3 (HPLC + LC-ESI-QIT MS). The core- (A) and membrane-enriched (B) fractions were resolved on a C4 HPLC column according to the Methods section. Tandem mass spectrometric analysis of fraction 59–60 (B, indicated by brackets) produced from a singly charged precursor ion (inset, m/z 1289.7), yielded fragment ions which corresponded to a peptide the L1R protein. Asterisks (*) denote the loss of ammonia (NH3) or water (H2O).
