WebPeptide mass fingerprinting (PMF) (also known as protein fingerprinting) is an analytical technique for protein identification in which 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 method was developed in 1993 by … WebJan 1, 2016 · MALDI-TOF MS measures a fundamental physical property of the analyte itself, i.e., its mass or more accurately its m/z. Most other widely practiced assays (e.g., ELISA and colorimetric assays) measure signals generated secondary to the analyte, and often as a result of a chemical or physical interaction.
