  2. Cultivation Of CHO Suspension Cells And SEAP Expression

    This application note describes the cultivation of CHO suspension cells in the wave-mixed Thermo Scientific HyPerforma Rocker Bioreactor with a maximum working volume of 5 L. 

  3. Gemin X Pharmaceuticals: Finding A Drug's Mechanism Of Action

    Gemin X, a pharmaceutical company focused on the discovery and development of advanced oncology
    therapeutics, approached Metabolon to run a metabolism profile for one of their compounds—GMX1777.

  4. White Paper: Computrac® Moisture Analysis Made Simple 8/10/2011
    When people aren’t feeling their best they often turn to medicine for relief from the symptoms that are associated with being ill. The public trusts that the products by pharmaceutical companies will not only make them feel better but will also not have harmful side effects.
  5. White Paper: Comparability Of The Cell-Freeze® (Charter Medical) Freezing Bag To The Cryocyte™ (Baxter) Bag For Cryogenic Storage Of Human Hematopoietic Progenitor Cells 7/11/2011
    Successful cryopreservation of hematopoietic progenitor cells (HPC) is dependent upon a number of factors, including the biopreservation media, freezing rates, and storage using sterile, cryogenically durable storage bags. The Cell-Freeze® cryogenic storage containers are 510(k) cleared for storage, preservation and transfer of hematopoietic progenitor stem cells (HPC’s). By Charter Medical, Ltd.
  6. Rapid Chemically-Defined Feed Media Development to Improve Simulated Cell Culture Processes

    Implementing an optimized feed medium may be the most effective alternative for modifications to the growth medium in an existing process.

  7. Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor System 10/24/2013

    This application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.

  8. Protein A Alternatives: Mixed Mode Resins For High Throughput mAb Feedstocks 8/16/2012

    Mixed mode resins can serve as an alternative to protein A in intermediate processing. Implementation of mixed mode resins can reduce water required for filtration and time  for column loading.
     

  9. Accelerating Biopharmaceutical Development From DNA To Drug 7/8/2016

    In the last decade, single-use solutions for virtually every bioprocess unit have been developed, and considerable investments have been made by the industry into areas that underpin this technology.

  10. 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.
