PRM Quantitative Proteomics Services

Parallel Reaction Monitoring (PRM), an alternative method to SRM/MRM, is a targeted quantification method performed on hybrid quadrupole-Orbitrap (q-OT) and quadrupole time-of-flight (q-TOF) mass spectrometers. PRM has comparable sensitivity with similar linearity, precision, repeatability and dynamic range for protein quantification compared with SRM, but PRM provides high specificity, high selectivity, high accuracy and high-throughput quantification with confident targeted protein/peptide confirmation. It is ideal for quantifying tens to hundreds of targeted proteins/peptides in complex matrices.

PRM technology uses the quadrupole of Orbitrap or Q Exactive mass spectrometer to separate the target precursor ion before fragmenting the targeted precursor ion in the collision cell. The product ions can then be detected in the Orbitrap mass analyzer. This allows for accurate specificity analysis of the target proteins/peptides in complex samples.
