MINNEAPOLIS, Jan. 26, 2023 /PRNewswire/ -- Bio-Techne Corporation (NASDAQ: TECH) today announced the launch of its ProteinSimple-branded MauriceFlex™ during the WCBP conference in Washington D.C. MauriceFlex™ enables protein charge variant fractionation plus routine cIEF & CE-SDS assays, making it a unique multi-functional system that further streamlines protein characterization workflows.

In-depth characterization of protein charge variants is critical to identify post-translational modifications (PTMs), as some PTMs impact a molecule's therapeutic functionality. These variants need to be separated and collected for further analysis by biochemical and biophysical techniques. Capillary isoelectric focusing (cIEF) is the gold-standard for charge variant analysis, and MauriceFlex™ enables cIEF-based fractionation in the same day, precluding the need for method development, fractionation, and data bridging with ion-exchange chromatography (IEX) or other methods. MauriceFlex™ can run samples with urea, a feature that is missing in current capillary electrophoresis-mass spectrometry coupled methods. The MauriceFlex™ fractionation enables direct analysis of collected fractions without any mass spectrometry sample preparation for extended characterization. In addition, MauriceFlex™ provides great freedom and flexibility to a scientist by enabling routine cIEF and CE-SDS assays on the same system that can further characterize the charge variant peaks with fractionation and mass spectrometry.  

At the WCBP conference, a major international biotech company presented their MauriceFlex™ data to evaluate the thermal degradation pathway of a therapeutic dual variable domain antibody called DVD-Ig™. They used MauriceFlex™ fractionation followed by MS characterization of the charge variant fractions to identify the modification(s) responsible for the thermal degradation.

"MauriceFlex™ enables our customers to understand their therapeutic molecule faster, improving their chances of reaching the market first," said Will Geist, President of Bio-Techne's Protein Sciences Segment. "Our goal is to continuously simplify protein analysis for our customers so that they can proceed confidently and quickly across the different stages of drug development. MauriceFlex™, with its fractionation capabilities, lets scientists gather the data they need to make informed decisions much faster."
