Mass spectrometry (MS)-based proteomics remains technically demanding and prohibitively expensive for many large-scale or routine applications, with per-sample costs of hundreds of dollars or more. To democratize access to proteomics and facilitate its integration into more high-throughput multiomic...
Fast photochemical oxidation of proteins (FPOP) is a modern technique for studying protein folding, conformations, interactions, etc. In this work, timsTOF Pro mass spectrometer coupled with trapped ion mobility spectrometry was used for identification of oxidative modifications in a model protein. ...
This study aimed to investigate the human tear proteins extracted from whole (W) Schirmer strips (ScS) and their two parts, the bulb (B) and the rest of the strip (R) with a comprehensive proteomic approach using a trapped ion mobility mass spectrometer, the timsTOF Pro. Eight ScS were collected fro...
Objective: To investigate the mechanism of ultra-high dose rate pulsed radiation in radiation-induced lung injury (RILI), providing an experimental and theoretical basis for the application of FLASH-RT in radiotherapy. Methods: C57BL/6J mice were randomly divided into three groups: a sham group, a F...
Next-generation mass spectrometry platforms (Orbitrap Astral, timsTOF Ultra) are reshaping proteomics by enhancing analytical depth and sensitivity. We compared these platforms against Orbitrap Exploris 480 using neonatal mouse lung tissue from a bronchopulmonary dysplasia model (n=12), employing fo...
Untargeted metabolomics is a popular method by which researchers measure a large portion of the metabolites present in a biological system at once. This approach usually results in complex data sets containing tens to hundreds of thousands of observations whi...
