Generation and Characterization of Six Recombinant Botulinum Neurotoxins as Reference Material to Serve in an International Proficiency Test.
40 subtypes. Expert laboratories currently use different technical approaches to detect, identify and quantify BoNT, but due to the lack of (certified) reference materials, analytical results can ...
Development and performance assessment of a qualitative SYBR® green real-time PCR assay for the detection of Aspergillus versicolor in indoor air.
indoor airborne fungal contamination is a common tool to help understanding the link between fungi in houses and respiratory problems. Classical analytical monitoring methods, based on cultivation and ...
Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium
routinely monitored in targeted chemo-analytical methods and can detect them at low amounts (pg/L EEQ, Estrogen EQ uivalence). The bioassay used in this study is the CALUX (Chemically activated luciferase ...
Physical Characterization of Nanomaterials in Dispersion by Transmission Electron Microscopy in a Regulatory Framework
specimens to obtain a representative distribution of particles on the grid is discussed. The application of TEM imaging methods, electron diffraction and analytical TEM to obtain complementary information on ...
Determination of selected veterinary antimicrobials in poultry excreta by UHPLC-MS/MS, for application in Salmonella control programs.
zoonotic Salmonella spp. To uncover illicit use, an analytical method using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC- MS / MS) for the determination of antimicrobial ...
Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
