Is MS1 necessary in DIA?

Is MS1 utilized in DIA-MS? During a DIA-MS experiment, MS1 scans are usually acquired. For the TOF-based DIA-MS experiments, MS1 scans are usually of moderate resolution. For example, the original SWATH-MS paper (PMID: 22261725) by Gilet et al used 250-ms to finish a DDA-MS1 scan while 100-ms to finish a SWATH-MS1 on a TOF-MS system. Considering that each scan, regardless of MS1 or MS2 in SWATH, takes 0.1 s, SWATH-MS1 takes around 3.3% of the cycle time. The authors did, however, additionally de…read more

Liquid Chromatography For Trace Proteomics: A Mini-review

Please note that authorship is reserved, and you must have my consent before reproducing this article. Technology has been a main driven power prompting development of system biology study. In the acquisition of proteomic digital data, a separation method in conjugation with tandem mass spectrometry is an optimal combination given that mass spectrometry cannot handle thousands of peptides flowing inside at the same time. The following content presents a mini-review for several separati…read more
