Downstream Processing White Papers and Case Studies

  1. Automated Bioluminescent ADCC Reporter Bioassay Using Bioengineered Jurkat Cells 2/10/2013

    Pharmaceutical companies are increasingly exploring new biologic and biosimilar products, and thus increasing monoclonal antibody (mAb) immunotherapeutic research. By Tracy Worzella, Promega Corporation and Brad Larson, Applications Department, BioTek Instruments, Inc.

  2. Cultivation Of Human CAP Cells: Evaluation Of Scale-Down Capabilities 4/18/2016

    The following application note illustrates how the DASbox Mini Bioreactor System combined with the BioBLU 0.3c single-use vessels supports bioprocess development in human cell culture.

  3. Biological Contamination Events In Isolators: What Lessons Can Be Learned? 8/17/2012

    Microbiological deviation and biological contamination events have been observed in pharmaceutical isolators including those used in production, sterility test and pharmacy aseptic services. By James Drinkwater, Bioquell UK Process & Compliance Director

  4. Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion 3/26/2012

    The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.

  5. A Purification Strategy For Clinical-Grade Monoclonal Antibody 10/3/2016

    mAbs are currently the most important class of therapeutic proteins. Advances in upstream process technologies have led to tremendous improvement of mAb titers in mammalian cell culture. 

  6. SciLog - Creating Advanced Biotech Equipment With Mettler Toledo 3/26/2012
    For nearly two decades, SciLog, Inc. has been dedicated to creating revolutionary single-use purification systems and disposable sensor technologies.
  7. Important Considerations For Implementing A Single-Use Biomanufacturing Strategy 10/18/2013

    Recent trends in biomanufacturing technology and the biopharmaceutical market are supporting the increased adoption of single-use (SU) manufacturing systems. On the demand-side, the biopharma industry is focusing on niche and rare diseases with smaller patient populations, resulting in the need for smaller, more agile biomanufacturing capacity. By Jodi M. Zobrist and Nicole W. O'Brien, Ph. D., Gallus Biopharmaceuticals, LLC

  8. Monoclonal Antibody Purification Platform Using High-Capacity Protein A And Mixed-Mode Chromatography 10/1/2016

    The first step in purification of an important class of therapeutic proteins, the polyclonal or monoclonal antibodies (mAbs), is their capture from plasma or tissue culture supernatants. Protein A–based media are by far the most common class of affinity products used for this purpose.

  9. Important Parameters For Packing Nuvia HR-S Resin At Process Scale 5/27/2020

    Process-scale production typically involves more than one column. The packing quality of each column affects the efficiency of the whole workflow and is an important validation criterion.

  10. Mammalian Virus Purification Using Ceramic Hydroxyapatite

    Conventional techniques for mammalian virus purification produce variable quality, quantity, and significant loss of particle infectivity. We  propose the chromatographic separation of viral particles of diverse sizes and from different families such as dengue, influenza, mouse hepatitis, adenovirus, poliovirus using CHT Ceramic Hydroxyapatite resin.
