We got the opportunity to talk to Aaron Bailey at BGI Americas. From their newly setup MS labs, they use SmartEnzymes to help provide analytical services to their customers globally. Read on to find out more. Tell us about yourself and BGI? Currently I work at BGI Americas as the Associate Director of Product Management for Mass Spectrometry…
Johny joined the Genovis team in August, and he brings more than 25 years of financial experience to the company. We are very excited to have you in the team, Johny! Welcome! Tell us a bit about yourself I live in Malmö, in the southern part of Sweden and I have two daughters. I…
Protein charge is a fundamental property that influences both the ability to interact with other molecules and the structure, solubility and stability of the protein. In this collaborative work by Boehringer Ingelheim Pharmaceuticals, Janssen BioTherapeutics and University of New Hampshire, the charge measurements of twelve monoclonal IgG and their F(ab’)2 and Fc fragments are…
We have received an order for SmartEnzymes that will be used in the manufacturing process for a biological drug.
Radioactively labelled antibodies are excellent immuno-PET tracers for evaluating in vivo distribution and performance of therapuetic agents. Site-specific conjugation at the antibody Fc glycan site by enzymatic remodeling allows for a uniform label distribution of such PET-tracers, compared to conjugates generated with conventional random labelling strategies. In an article by Kristensen et al. (2019), the…
The use of capillary electrophoresis for the analysis of therapeutic antibodies and other biopharmaceuticals is growing in popularity. A new article by researchers from CNRS in France showed how capillary zone electrophoresis-native mass spectrometry could be used for the quality control of intact therapeutic monoclonal antibodies. The authors show for the first time the use of a triple layer coated…
Many of Genovis' customers have submitted abstracts for ASMS 2019 in Atlanta, in which the SmartEnzymes have been used. Below is a digested guide to these abstracts so that you can plan your days at ASMS. To read the full poster abstracts, visit the Online Planner for ASMS, and paste the abstract titel in the search field. Sunday,…
In biopharmaceutical product development and manufacturing, free thiol content is one of the product quality attributes of interest as its presence could impact structure, stability and function of the product. At Biogen, Yi Pu et al have optimized a label-free LC (UV) / MS method for free thiol quantification at a subunit level of IgG1…
Analysis of the glycosylation of therapeutic antibodies and other biopharmaceuticals is typically done by LC or LC/MS-based methods. However, each analytical technique has its strengths and weaknesses which makes the development of orthogonal methodologies crucial for in-depth characterization. In this study, researchers from the FDA present a middle-down NMR approach for studying glycosylation of therapeutic antibodies. Analogous to…
The Consortium for Top-down Proteomics is currently conducting a large inter lab study. They are developing methods for the analysis of intact mAbs and antibody subunits generated by digestion with either FabRICATOR or GingisKHAN. In this paper, van der Burgt et al. present a novel method for the analysis of mAbs based on MALDI in-source…
Genovis was selected to present at the GlycoBioTec 2019 Conference in Berlin in January. Andreas Nägeli, Senior Scientist at Genovis, presented novel workflows based on the O-glycan specific OpeRATOR enzyme and GlycOCATCH coupled to LC-MS. Download the slide deck here Read more about Operator
In an article by Valentina D’Atri et al. recently published in Analytical Chemistry (2019), the scientists developed a middle-up HILIC/HRMS workflow for detailed characterisation of the Fc fusion protein etanercept. The etanercept molecule consists of an IgG1 Fc domain fused to a tumour necrosis factor receptor (TNFR) and is used in the treatment of…
