Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
Han, Zheng Source: Toxins, Volume 11, Issue 2, Number 100 (2019) Keywords: Alternaria toxins Grape modified QuEChERS UHPLC-MS/MS Abstract: A simple and reliable analytical method for the simultaneous ...
A more sensitive, efficient and ISO 17025 validated Magnetic Capture real time PCR method for the detection of archetypal Toxoplasma gondii strains in meat.
demonstrated. For this, a bioassay is still the reference method. As an alternative, various PCR methods have been developed, but due to the limited amount of sample that can be tested, combined with a low tissue ...
Nicotine Dependence and Urinary Nicotine, Cotinine and Hydroxycotinine Levels in Daily Smokers.
cigarettes per day among biomarker concentrations and individual FTND items. METHODS: Urine samples and questionnaire data of 239 daily smokers were obtained. Nicotine, cotinine and hydroxycotinine urinary ...

Current and new approaches in GMO detection: challenges and solutions
https://www.sciensano.be/nl/biblio/current-and-new-approaches-gmo-detection-challenges-and-solutions
DNA, have been developed to implement these legislations. Due to its numerous advantages, the quantitative PCR (qPCR) is the method of choice for the enforcement laboratories in GMO routine analysis. ...
Integrated DNA walking system to characterize a broad spectrum of GMOs in food/feed matrices.
methods targeting p35S or tNOS, the most common transgenic elements found in GM crops, were developed. These newly developed DNA walking methods are completing the previously implemented DNA walking method ...
Statistical framework for detection of Genetically Modified Organisms based on Next Generation Sequencing
number and diversity of genetically modified (GM) crops has significantly increased, their analysis based on real-time PCR (qPCR) methods is becoming increasingly complex and laborious. While several ...
Determination of selected veterinary antimicrobials in poultry excreta by UHPLC-MS/MS, for application in Salmonella control programs.
was selected and administered in the drinking water to two laying hens. Excreta samples were collected every 12 h during and until 2 days after treatment and analyzed using the developed method. Health ...
Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
spectrometry (UHPLC- MS / MS) method was developed to measure creatinine in small volumes of human urine. In this method, urine samples are simply diluted with a basic mobile phase and injected directly under ...
New trait-specific qualitative SYBR®Green qPCR methods to expand the panel of GMO screening methods used in the CoSYPS
PCR (qPCR) methods were developed and in-house validated: one method is element-specific and targets the Cry3Bb trait, and the other one is a construct-specific method detecting the gat-tpinII junction. ...
