ProteomicsDevelopment of sequential sample processing protocol on a single anion-exchange solid-phase extraction disc for bottom-up/cross-linking mass spectrometry
In this project, we developed a rapid enzymatic digestion protocol within an anion exchange StageTip named AnExSP (anion-exchange disc-assisted sequential sample preparation) and, using data-independent acquisition, analyzed its digestion performance of human cellular protein extracts (HCPE) using t...

ProteomicsPEPPI-SP3: Robust and Simple Sample Prefractionation Workflow for Top-Down Proteomics
In this study, we developed a complete, robust, and simple sample preparation workflow named PEPPI-SP3 for top-down proteomics by combining PEPPI-MS with the magnetic bead-based protein purification approach used in SP3 (single-pot, solid-phase-enhanced sample preparation), now one of the standard s...

ProteomicsBAC-DROP: Rapid digestion of proteome fractionated via dissolvable polyacrylamide gel electrophoresis and its application to bottom-up proteomics workflow
The GeLC-MS workflow, which combines low-cost, easy-to-use SDS-polyacrylamide gel electrophoresis (SDS-PAGE) with liquid chromatography-mass spectrometry (LC-MS), is very popular in current bottom-up proteomics. However, GeLC-MS requires that PAGE-separated proteins undergo overnight enzymatic diges...

ProteomicsQuantitative assay of targeted proteome in trichome glandular cells using large-scale selected reaction monitoring strategy
Background: Glandular trichomes found in vascular plants are called natural cell factories because they synthesize and store secondary metabolites in the glandular cell. In order to systematically understand the metabolic processes in the glandular cells, it is indispensable to analyze the cellular ...

ProteomicsSynthetic biology meets proteomics: Construction of à la carte QconCATs for absolute protein quantification
We report a new approach to the assembly and construction of QconCATs, quantitative concatamers for proteomic applications that yield stoichiometric quantities of sets of stable isotope-labelled internal standards. The new approach is based on synthetic biology precepts of biobricks, making use of l...
