Tandem mass tags (TMTs) have increasingly become an attractive technique for global proteomics. However, its effectiveness for multiplexed quantitation by traditional tandem mass spectrometry (MS<sup>2</sup>) suffers from ratio distortion. Synchronous precursor selection (SPS) MS<sup>3</sup> has been widely accepted for improved quantitation accuracy, but concurrently decreased proteome coverage. Recently, a Real-Time Search algorithm has been integrated with the SPS MS<sup>3</sup> pipeline (RTS  ...[more]
