A Selected reaction monitoring protocol for the measurement of sTREM2 in cerebrospinal fluid

• Mass spectrometry plays an increasingly important role in the biomarker field with the advent of targeted proteomics. Tryptic peptides from a protein of interest can be used to create a targeted assay to interrogate cerebrospinal fluid (CSF) for biomarkers. Since heterozygous mutations in the TREM2 gene have been associated with an increased risk of Alzheimer’s disease, measuring this soluble protein in CSF has become a priority. This chapter demonstrates the development, optimization, and validation of a method to measure soluble TREM2 using a single reaction monitoring (SRM) targeted mass spectrometry assay. © 2018, Springer Science+Business Media, LLC.
