Validation of the CALUX bioassay for PCDD/F analyses in human blood plasma and comparison with GC-HRMS.
analyses. The limit of quantification (LOQ) used to calculate TEQ values from the GC- HRMS determinations, the use of the relative potency values instead of the toxic equivalent factor and the potential of ...
Using an oilseed rape x wild/weedy relative gene flow index for the monitoring of transgenic oilseed rape
these values, monitoring priorities can be defined within the pool of cross-compatible wild /weedy oilseed rape relatives. It is discussed how the numerical quantification may serve as a valuable tool in ...
Comparison of Droplet Digital PCR and qPCR for the Quantification of Shiga Toxin-Producing Escherichia coli in Bovine Feces.
absolute quantification independent from any reference material and is less prone to PCR inhibition than qPCR. In this study, the qPCR-based protocol described by Verstraete et al. (2014) for Shiga toxin ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical methods using spiked samples at three concentration ...
A High-Throughput Yellow Fever Neutralization Assay.
throughput, the classical plaque reduction neutralization test (PRNT) is still considered the gold standard for the detection and quantification of nAbs due to its sensitivity and specificity. Here, we report ...
SARS-CoV-2 neutralising antibody testing in Europe: towards harmonisation of neutralising antibody titres for better use of convalescent plasma and comparability of trial data.
10-fold. The harmonisation of neutralising antibody quantification is a vital step towards determining the protective and therapeutic levels of neutralising antibodies. Health Topics: Coronavirus ...
Determinants of persistent organic pollutant (POP) concentrations in human breast milk of a cross-sectional sample of primiparous mothers in Belgium
organochlorine compounds (p,p′- DDT, p,p′- DDE, HCB and β- HCH) and two brominated flame retardant congeners (BDE-47, BDE- 153) were detected at concentrations above the limit of quantification in>50% of the breast ...
