Mass spectrometry is among the most powerful analytical techniques available for protein characterization.

Mass spectrometry (MS) of proteins is a powerful analytical technique used to identify, characterize, and quantify proteins by measuring the mass-to-charge ratio (m/z) of their ionized forms.

Research Area:

» Molecular weight (accurate mass) determination
» Protein Profiling of digested sample
» Identification of proteins from Gel
» Peptide Mass Fingerprinting
» Amino Acid Composition Analysis

Peptide fingerprinting is a method used to identify proteins by comparing the masses of peptide fragments to a database of known protein digests. It’s typically done using MALDI-TOF mass spectrometry.
