WebDeveloped in 2002, Hydroxyl Radical Protein Footprinting (HRF) has a long track record of success in academic labs for protein structural studies. At Immuto Scientific, we are leveraging this powerful, highly validated technique to analyze protein-protein interactions and map epitopes with an unprecedented degree of speed, resolution and accuracy. Web1 mei 2024 · Hydroxyl radicals are a useful reagent for in vivo footprinting, but the low ambient oxygen levels inside cells reduces oxidation efficacy relative to in vitro studies. Possible approaches to overcome these limitations have been explored by Espino et al. , who used laser photolysis of peroxide to oxidize proteins inside cells ( 100 ).
WebHydroxyl radical footprinting (HRF) MS is an emerging technology orthogonal to HDX that, instead of detecting changes in the protein backbone, probes solvent accessible surface area (SASA) of protein side-chain residues. Web26 jun. 2024 · Fast photochemical oxidation of protein (FPOP) has become an important mass spectrometry-based protein footprinting approach. Although the hydroxyl radical (• OH) generated by photolysis of hydrogen peroxide (H 2 O 2) is most commonly used, the pathways for its reaction with amino-acid side chains remain unclear.Here, we report a …
