SRM-MRM Quantitative Proteomics Services

Selected Reaction Monitoring (SRM), also known as Multiple Reaction Monitoring (MRM), is used to monitor several selected precursor-fragment transitions of the targeted peptides. The selection of the SRM/MRM transitions is calculated based on the acquired data. SRM/MRM, using a triple quadrupole MS, consists of three steps: selection of targeted precursor peptides based on MS spectra, fragmentation one (or more) of these precursor peptides, and acquisition fragment ions based on MS/MS spectra. Up to 6000 transitions can be monitored by SRM/MRM technology. The advantages of SRM/MRM include flexibility, sensitivity, specificity and reproducibility, making it ideal for quantitative analysis which enables the precise quantification of protein networks in biological systems. Furthermore, SRM/MRM based quantification can be combined with different strategies for relative or absolute protein quantification.
