Protein quantitation by mass spectrometry
Targeted proteomics or Multiple Reaction Monitoring (MRM) LC-MS/MS analysis is a powerful technique that can multiplex the quantitation of multiple proteins in one analysis.
Essentially a protein or biomarker can be measured in a complex sample such as serum, CSF or urine by identifying a unique peptide sequence (proteotypic) that represents that protein. The sample is then digested using a protease to generate that peptide from the biomarker protein. The unique peptide is then measured using mass spectrometry. The mass spectrometer can measure many peptides at once so an assay can be 鈥榤ultiplexed鈥�

The TMSRG has extensive experience developing multiplex targeted proteomic assays
We have assays developed in CSF, urine serum/plasma to confirm biomarker or measure the inflammation profile.听
We are now using these assays to look at the effect of 听post 鈥揷ovid19 infection on healthcare workers in collaboration with Great Ormond Street, Barts and the Royal Free Hospitals.听
