摘要

In this note, we describe a method devised to detect, by means of mass spectrometry (MS), tryptophan-containing peptides and proteins using pyridine-borane. This reagent selectively reduces tryptophan residues, converting them to 2,3-dihydro-tryptophan, thereby enabling quantitation of tryptophans. Copyright © 2013 Elsevier Inc. All rights reserved.
