TL;DR: It is found that inactivation of Upf1p and Xrn1p causes common as well as unique effects on protein expression, and the use of 4-fold multiplexing to enable relative protein measurements simultaneously with determination of absolute levels of a target protein using synthetic isobaric peptide standards.
Journal ArticleDOI
LC-ESI-MS/MS Analysis of Testosterone at Sub-Picogram Levels Using a Novel Derivatization Reagent
TL;DR: A derivatization step involving a novel, permanently charged, quaternary aminooxy (QAO) reagent or MS-tag that reacts to the ketone functionality of testosterone and significantly enhances its ESI-MS/MS sensitivity is presented.
Patent
