Web13 okt. 2024 · Such protein variations are reflected in mass spectra of tested bacteria. For example, the MALDI-TOF MS fingerprinting of Y. enterocolitica gave similar profiles from cultures grown at 32°C and 37°C, and less similar from 26°C grown on various media (Wunschel et al., 2005). Web3 mei 2024 · In our study, nucleotide MALDI-TOF-MS has been proved to be a rapid test for drug susceptibility of MTB. Except for ethambutol (79.2%), the concordance between nucleotide MALDI-TOF-MS and phenotypic drug sensitivity results was more than 85.0%. WebDesorption Ionisation Acceleration Separation Detection (Courtesy of Paul Gates 2014)18 The basic procedure of MALDI-TOF MS is as stated: • the target plate is placed into the ionisation chamber of the mass spectrometer. Spots to be analysed are shot by an ultraviolet N2 laser desorbing microbial and matrix molecules from the target plate. maria galland 96 preisvergleich
