Automated processing of whole blood samples for the determination of immunosuppressants by liquid chromatography tandem-mass spectrometry [PDF]
Background: Liquid chromatography tandem-mass spectrometry (LC-MS/MS) is an efficient technology for routine determination of immunosuppressants in whole blood; however, time-consuming manual sample preparation remains a significant limitation of this ...

Determination of secoisolariciresinol diglucoside by high performance liquid chromatography
High performance liquid chromatography-photodiode array detection-elctrospray ionizationmass spectrometry (HPLC-PAD-ESI-MS) method was used to determine secoisolariciresinol diglucoside (SDG) qualitatively and quantitatively. Precision, stability, limits

Development and validation of an HPLC-UV method for purity determination of DNA
Determination of the concentration and the purity of DNAs is crucial for measuring the DNA copy number since it will influence further DNA analysis such as digital PCR (dPCR) and next-generation sequencing (NGS).

Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Integrated Nano Liquid Chromatography System On-a-Chip [PDF]
Integrated liquid chromatography (LC) chips are valued because of their significant advantages over conventional systems. However, they are very challenging to build due to the high complexity of LC systems and the need for high-level integration of many

Tau acetylation at K331 has limited impact on tau pathology in vivo
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
