Targeted Proteomics

Methods Mol Biol. 2019:1871:265-277. doi: 10.1007/978-1-4939-8814-3_17.

Abstract

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). In this report, we describe the details of quantitative analysis of target protein in cells and tissue samples.

Keywords: Cells and tissue samples; Liquid chromatography-tandem mass spectrometry; Protein quantification; Targeted proteomics.
