PMID: 29273904
DOI: 10.1007/s00216-017-0750-7

[…] of lc–hrms data was performed with xcalibur 2.1.0 qualbrowser, and for relative and absolute quantification of known analytes xcalibur 2.1.0 quanbrowser was used. data were further evaluated with metextract [], which was programmed to automatically extract the corresponding ms peak pairs in mass spectra of a 1:1 mixture of the sample containing12c toxin and 13c-labeled toxin. the metabolites […]

[…] is unique and can therefore be efficiently used for artifact detection. extracts were analyzed by lc-hrms and data processing was performed with a customized version of the in-house developed metextract ii software []. the software was used to automatically screen for pairs of native (12c) and fully-13c-labeled artifacts (mm and m’m—) and their respective isotopologs (mm + 1 and m’m − 1). […]

[…] of targeted and untargeted processing of labeled datasets, and the output includes a set of plots summarizing the pattern of labeling observed per peak, allowing users to quickly explore data. metextract [] relies on a mixture of cultures from the same organism under natural and labeled media to select signals that show a clear pattern of isotopic enrichment. however, the approach requires […]

PMID: 28449301
DOI: 10.1002/cbic.201700093

[…] the trna wobble base modification 5‐methoxycarbonylmethyl‐2‐thiouridine (mcm5s2u) lead to codon‐biased gene‐expression changes in starved animals. we based our method on the powerful software tool metextract, originally developed for the automated extraction of metabolite‐derived lc‐ms signals from lc‐hrms full‐scan data obtained from isotopically labelled biological samples. we reasoned […]

PMCID: 5198558
PMID: 27929394
DOI: 10.3390/toxins8120364

[…] for qualitative screening based on plant-treatment with a mixture of native and 13c-labelled toxin, lc-orbitrap-ms analysis in positive and negative ion mode and automated data processing by metextract ii software []. further structural information of the formed toxin derivatives was gained by lc-hrms/ms measurements with a lc-q-tof-system. within the scope of a time course experiment, […]
