Purpose: To develop a high accuracy, sensitivity, robustness and speed biomarker discovery and verification workflow based on a Tandem Mass Tag™ (TMT™) quantitation approach and transfer of retention time information into label-free quantitation using peptide retention prediction. Methods: The depleted plasma from three normal and three diabetic patients was digested and analyzed in parallel using TMT-based and label-free methods. TMT-labeled peptides were fractionated and analyzed on a Thermo Scientific™ Orbitrap Fusion™ mass spectrometer (MS). Analysis of non-labeled peptide mixtures was performed using 1D LC-MS on a Thermo Scientific™ Q Exactive™ HF-X hybrid quadrupole-Orbitrap™ mass spectrometer. Results: 48 potential biomarker proteins were found in diabetic patients using a TMT-based discovery workflow and validated by targeted label free peptide quantification.
