• Quantitation of monoclonal antibody infliximab in human plasma by LC-MS/MS using Fab-selective limited proteolysis nSMOL technology

    Infliximab, known commercially as Remicade, is a chimeric IgG1 kappa monoclonal antibody (mAb) that targets tumor necrosis factor-alpha (TNF).
    In studies conducted, a significant number of patients (30-40%) who did not respond to anti-TNF treatment were identified.

    Instrument: LCMS-8060 Liquid Chromatography Mass Spectrometer (LCMSMS)

  • Povidone, Formic Acid Test (USP/EP/JP)

    Povidone (polyvinylpyrrolidone, PVP) is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs. It additionally acts as a disintegrant and tablet binder.

    The revision to the harmonized standard for Povidone has been approved and Formic Acid in Povidone is now required to be measured.

  • ProteaseTag ™ Active NE Immunoassay: A Rapid Test for the Quantification of Neutrophil Elastas Levels in Patients

    Oliver Carney, BMG LABTECH Ltd, Aylesbury, UK; Kelly Moffitt and Charlene Robb, ProAxsis, Belfast, Northern Ireland, 02/2016

    The neutrophil elastase is a biomarker of respiratory diseases such as cystic fibrosis (CF) or chronic obstructive pulmonary disease (COPD). A simple, rapid and accurate test for neutrophil elastase levels in patient samples would be a significant medical benefit. Established methods do not specifically verify the presence of the enzyme leading to a high value of false positives. In this application note we show how to use the ProteaseTag™ Active Neutrophil Elastase Immunoassay from the company ProAxsis which is based in Northern Ireland. 

    The assay uses tags to specifically bind the enzyme of interest. Chromogenic detection is performed with the CLARIOstar® microplate reader which analysis the results and return qualified data automatically. 

    Protease levels can be determined in sputum sol, bronchoalveolar lavage, wound exudate or serum free cell culture.
