Peptide Mass Fingerprinting (PMF) - proteomics - 03-16-2015
Peptide mass fingerprinting (PMF) is an analytical technique for protein identification. Basically, the unknown protein of interest is first cleaved into smaller peptides, whose absolute masses can be accurately measured with a mass spectrometer such as MALDI-TOF or ESI-TOF.
The advantage of PMF method is that only the masses of the peptides is need to be known, while time-consuming de novo peptide sequencing is then unnecessary, as long as the protein sequence is present in the database of interest.
