Dietary exposure to pyrrolizidine alkaloids in young children and adults from the Belgian population (PASFOOD)

methods was required to detect the presence of PA s at ppb or even ppt levels.   Analytical methods based on analytes extraction and SPE purification, followed by UPLC separation and MS / MS detection were ...

Global transcriptional analyses of Mycobacterium tuberculosis using old and new drugs

of the drug.  RNA was extracted combining bead-beating in TRI zol and the Direct-Zol purification kit. After quality control, the extracts were fragmented, barcoded and pooled, cDNA libraries were ...

Global transcriptional analyses of Mycobacterium tuberculosis using old and new drugs

bead-beating in TRI zol and the Direct-Zol purification kit. After quality control, the extracts were fragmented, barcoded and pooled, cDNA libraries were constructed and sequenced using the HiSeq technology ...

Detection of pyrrolizidine alkaloids in milk and honey on the Belgian market using UHPLC-MS/MS.

were developed for the analysis of 16 PA s and 13 PANO s in honey and milk matrices at WIV- ISP. The sample preparation involves acidic extraction of the analytes followed by SCX- SPE purification to ...

Scalable chromatography-based purification of virus-like particle carrier for epitope based influenza A vaccine produced in Escherichia coli.

downstream processes. In particular, a rapid low cost purification process has been identified as a remaining key challenge in manufacturing process development. In the present study we set up a size-exclusion ...

Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.

positive electrospray ionization (ESI) conditions, without further purification steps. The combination of an important diluting factor (10(4) times) due to the use of a very sensitive triple quadrupole mass ...

Systematic identification of hypothetical bacteriophage proteins targeting key protein complexes of pseudomonas aeruginosa

Using affinity purifications of these host protein complexes coupled to mass spectrometric analyses, 37 host complex-associated phage proteins could be identified. Importantly, eight of these show an ...
