Different calibration strategies are used in liquid chromatography hyphenated to mass spectrometry (LC-MS) bioanalysis. Currently, the surrogate matrix and surrogate analyte represent the most widely used approaches to compensate for the lack of anal

Analysis of Neuron–Specific enolase isozymes in human serum using immunoaffinity purification and liquid chromatography–tandem mass spectrometry quantification

Autor: Genet, Sylvia A.A.M., Wolfs, Jur R.E., Vu, Chris B.A.K., Wolter, Madita, Broeren, Maarten A.C., van Dongen, Joost, Brunsveld, Luc, Scharnhorst, Volkher, van de Kerkhof, Daan

Publikováno v: Journal of Chromatography, B, Analytical Technologies in the Biomedical and Life Sciences, 1223:123701. Elsevier

Neuron–specific enolase (NSE) is a promising small–cell lung cancer (SCLC) biomarker composed of αγ and γγ isozyme dimers. As the conventional immunoassays are prone to interferences and cannot differentiate between the isozymes, we developed

Toxins; Volume 14; Issue 8; Pages: 567

Raw feed materials are often contaminated with mycotoxins, and co-occurrence of mycotoxins occurs frequently. A total of 250 samples i.e., rice bran and maize from Cambodia, Laos, Myanmar, and Thailand were analysed using state-of-the-art liquid chro
