synonym: mass mapping
https://doi.org/10.1351/goldbook.12522
Method for protein analysis where an unknown protein is chemically or enzymatically cleaved into peptide fragments whose masses are determined by mass spectrometry. The peptide masses are compared to peptide masses calculated for known proteins in a database and analyzed statistically to determine the best match.
