Mass Spectrometry (Proteomics)

Syllable breakdown

Dictionary meaning

An analytical technique that measures the mass-to-charge ratio of ions to identify and quantify molecules in a complex mixture. In proteomics, mass spectrometry is used to identify proteins, determine their amino acid sequences, and characterize post-translational modifications at high sensitivity and throughput.

Examples

• Mass spectrometry allowed researchers to identify thousands of proteins in a single blood plasma sample.
• The team used mass spectrometry to confirm the phosphorylation sites on the signaling protein.
