reaction monitoring (MRM), also known as selected reaction monitoring (SRM), and parallel
reaction monitoring (PRM) are targeted proteomics technologies aimed at quantifying up to
hundreds of proteins in the same
Multiple reaction monitoring
In an MRM workflow,
proteins are analyzed on a triple quadrupole mass spectrometer. The quadrupole
1 (Q1) is used as a mass filter to select a given precursor which is fragmented
in quadrupole 2 (Q2). In quadrupole 3 (Q3) a predefined number of product ions
from every precursor are analyzed. This enables highly sensitive protein
quantification over seven orders of magnitude.
Parallel reaction monitoring
PRM differs from MRM on the fact that all fragment ions instead of only selected ones are measured after
fragmentation of a selected precursor. For this reason, PRM is typically performed on Orbitrap or Time of Flight (ToF) analyzer.
Are MRM and PRM suitable to do absolute quantification?
Both technologies are suitable to perform absolute quantification by
using stable isotope heavy labeled reference peptides spiked into the sample at
