Mass spectrometry is an analytical technique in which samples are ionized into charged molecules and ratio of their mass-to-charge (m/z) can be measured. In MALDI-TOF mass spectrometry, the ion source is matrix-assisted laser desorption/ionization (MALDI), and the mass analyzer is time-of-flight (TOF) analyzer Cross-linking mass spectrometry (XL-MS) has received considerable interest, owing to its potential to investigate protein-protein interactions (PPIs) in an unbiased fashion in complex protein mixtures.
