This EMBO Practical Course aims to fill in the gap between theory and the actual implementation of the 2015-11-17 · For a targeted proteomics assay, it is often not trivial to reconnect surrogate peptides to a precise protein of origin due to the presence of shared proteolytic peptides from protein isoforms. Targeted proteomics is a technology for detecting proteins of interest with high sensitivity, quantitative accuracy and reproducibility. The analysis of a pre-defined group of proteins provides precise, quantitative and sensitive data to scientists and clinicians and can provide information on a subset of proteins important for their biological function. Targeted proteomics helps researchers build on this knowledge and focus their experiments on the subset of proteins important to their line of inquiry.
Targeted proteomics detects proteins of interest with high sensitivity, quantitative accuracy, and reproducibility. In a targeted proteomics assay, surrogate peptides are generated by proteolytic digestion of target proteins and selected reaction monitoring (SRM) assays are developed to quantify these peptides using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The targeted proteomics approach differs fundamentally from the more familiar 'shotgun' approach in which the spectra generated from all detectable proteins in a sample are interpreted by database 2019-04-24 Selected reaction monitoring (SRM) is a technique for targeted quantitative proteomics by mass spectrometry. Unlike shotgun proteomics experiments, the targeted proteomics approach requires information about the analyte prior to the analysis.
