  • Automating Protein Purification Processes Achieves Reliable Results And Reproducibility

    ÄKTA start is an easy-to-use, reliable protein purification system. In this application note it is described how Erica, a post-doctoral researcher, used ÄKTA start to purify GST-tagged protein using a predefined method template, a GSTrap FF column, and a Frac30 fraction collector. 

  • Optimized Sterile Filtration of Pharmaceutical Solutions

    The cost of filtration and separation stages within the production of pharmaceuticals has been increasing along with the increased complexity of final drug products.

  • Managing Cell-Based Potency Assays: From Development To Lifecycle Maintenance

    Characterization of a biological product — which includes the determination of physicochemical properties, biological activity, immunochemical properties, purity and impurities — is necessary to establish the safety and efficacy profile of a given product (ICH Q6B).  By Dr. Weihong Wang, manager, Molecular and Cell Biology, Eurofins Lancaster Laboratories

  • Efficiency Test Of ReadyToProcess™ Columns

    ReadyToProcess™ columns are prepacked, prequalified, and presanitized process chromatography columns suited for purification of biopharmaceuticals (e.g., proteins, vaccines, plasmids, and viruses) for clinical phase I and II studies. ReadyToProcess columns are available with several media at different volumes (1, 2.5, 10, and 20 L).

  • Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers

    Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings. By Ken Perrotta, Division Engineering Manager

  • Sani-Tech® Ultra White Paper

    For several years, pharmaceutical manufacturing professionals have increasingly stated concerns about material leachables and extractables and their impact on the products they produce. Fluid transfer systems that include flexible tubing have been at the forefront of this discussion.
