Molecular mass is the most fundamental characteristics for proteins and peptides. It directly reflects the structural integrity of proteins, and hence it is commonly applied in identification of proteins and peptides. To better assist the scientific research of our clients, MtoZ Biolabs provides macromolecular mass measurement service based on Bruker ultrafleXtreme™ MALDI TOF/TOF, and high-resolution protein mass measurement service via nano LC-MS. This service can be applied to calculate protein molecular weight accurately and analyze the molecular mass, subunits, and dimerization/polymerization of multiple biotechnological molecules, including proteins, peptides, antibodies, and vaccines, etc.
Application
• Measurement of the molecular mass of protein/peptide/antibody/vaccine, etc.
• Analysis of number of subunits in protein sample
• Analysis of dimerization/polymerization of protein sample
• Evaluation of sample purity and protein/peptide contaminants
Reports
• Experiment procedures
• Parameters of liquid chromatography and mass spectrometer
• MS raw data files
• Peptide identifications and intensity
• Protein identifications and intensity
