MALDI-TOF MS–based immunoassay using switching peptide for sensitive detection of intact foodborne bacteria
A matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS)–based immunoassay was developed for quantitative detection of five foodborne bacterial species: Escherichia coli O157:H7, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, and Bacillus cereus. The assay wa...
