Abstract: •prm-PASEF takes advantage of the trapped ion mobility technology for the targeted proteomics analysis.
•The sensitivity and selectivity of the acquisition method is improved by the ion mobility filtering and time focusing effect that happens during a PASEF acquisition.
• The massive parallelization capacity of the prm- PASEF approach allow to increase the number of targeted compounds while leaving sensitivity untouched.Summary: prm-PASEF is a new targeted acquisition method that fully exploits the multiplexing capability and the high resolution of the TIMS-TOF mass spectrometer. Multiple peptides can be sequentially measured from a single ion mobility scan without compromising the sensitivity.
