Downstream Processing White Papers and Case Studies

61. Removal Of Host Cell Proteins During Monoclonal Antibody Purification

    Protein A chromatography is a widely used and highly successful method of purifying recombinant monoclonal antibodies. However, since Protein A has high affinity for antibodies, harsh conditions such as low pH are often required to elute monoclonal antibodies from Protein A affinity columns. By 3M Purification Inc

62. Applications And Integration Of Hydrogen Peroxide Vapor For Biotech/Bioprocess

    The increase in size and scale of bio-processing is presenting a new challenge. Traditional methods of sterilisation, to maintain clean facilities, are becoming difficult to deploy in a controlled and regulatory compliant way. By Richard Lucas, Ph.D., Bioquell UK Ltd.

63. Met One Sensors Resistant To Vaporous Hydrogen Peroxide (VHP) 1/11/2012
    Pharmaceutical manufacturers often require an aseptic production environment to minimize the presence of microbes and their potential contamination of the manufactured product.
64. 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.
65. Single-Use Connections Advance Aseptic Processing

    John Boehm discusses how single-use connections advance aseptic processing and create increased process flexibility and reliability while reducing costs.

66. Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers 5/25/2012

    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

67. Best Practices For Process Scale Column Packing Of CHT™ Ceramic Hydroxyapatite Media

    CHT ceramic hydroxyapatite media require specific considerations during process-scale chromatography packing due to high specific gravity, rapid settling rate, and sensitivity to mechanical shear.

68. Agilent Microarray Grant Application Support White Paper 1/25/2012
    This guide offers an overview of Agilent’s microarray and SureSelect product offerings with ordering details to assist researchers with the details of grant submission.
69. 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. 

70. Proven Long Life Lasers™ In Optical Particle Counters 12/1/2011
    Optical particle counters (OPC) utilize light illumination and extinction to determine the presence, size, number and/or concentration of particles. Particles are typically suspended in a fluid or air, which flow through the volume that is illuminated and viewed by the detection system.
