WebSince the mass spectrometer randomly selects peptides for fragmentation, it is still challenging to consistently identify and quantify low-abundance peptides. An alternative strategy is the data-independent acquisition (DIA) in which all peptides within a defined mass-to-charge (m/z) window (for example, 12 Dalton) are fragmented [ 4 ].
