The second route is top-down analysis, where the mass of intact proteins is measured on a high accuracy MS instrument, and from the mass, protein modifications can be inferred due to a shift compared to the predicted mass in a protein database.”
Protein Identification using Mass Spectrometry
msf.ucsf.edutrypsin) for Peptide Mass Fingerprinting. • Use proteolysis, CID and peptide fragmentation to identify sections of protein sequence. (Bottom up). • Fragmentation analysis of the intact protein ‘Protein Sequencing’ (Top down). Not normally used for protein ID’s, more for PTM analysis. • All these approaches rely on database searching and

N-Glycan Analysis of Monoclonal Antibodies
iptonline.comoften used in glycan analysis (for example 6,7). The 2-AB-labelling is achieved by reductive amination, and results in a mass of the glycans of +119 Da. Due to protonation, the resulting mass shift is 120 Da (see Figures 2-4). Due to the hydrophilic properties of glycans, subsequent purification using Hydrophilic Interaction
