1 2D-LC-MS/MS analysis of tryptic digest of HEK293-SUMO3 cells (2 μg inj
2D-LC-MS/MS analysis of tryptic digest of HEK293-SUMO3 cells (2 μg inj.) using DIA and targeted identification with an inclusion list. 2D-LC-MS/MS analysis of tryptic digest of HEK293-SUMO3 cells (2 μg inj.) using DIA and targeted identification with an inclusion list.A, BPC, B, XIC for m/z , C, extracted fragment ion spectrum (precursor isolation window of m/z 950 ± 50) from which the mass of the SUMO3 peptide candidate was calculated to be Da based on the observation of the [M+3H]3+ ion at m/z for the peak eluting at 34.5 min. D, MS/MS spectrum (30 V collision energy) from the targeted analysis of [M+3H]3+ at m/z confirming the sequence of the SUMO3 peptide as ATGDETGAK(NQTGG)VERADGYEPPVQESV corresponding to 40S ribosomal protein S3a with a modified K249 residue.
