Downstream Processing White Papers and Case Studies

51. Selecting The Optimal Resins For The Process Purification Of Native And Recombinant Proteins 8/3/2016

    Native and recombinant proteins are used in a variety of applications ranging from drug discovery to target validation to high-throughput screening. Due to this, large-scale protein production and purification have become major necessities in industrial settings.

52. Managing Cell-Based Potency Assays: From Development To Lifecycle Maintenance 4/24/2012

    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

53. 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.
54. Chromatography Column Protection With 3M Purification LifeASSURE™ PLA Series Membrane Filters 9/14/2011
    Protective, or guard, filters are often used in chromatography column purification steps to protect the column media from contaminants in the various fluids that come in contact with the column.
55. Compound Profiling And Toxicity

    Utilizing a systems approach to drug discovery has generated a multitude of high affinity compounds for various classes of molecular targets with different degrees of disease state validation.

56. 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.

57. A Disposable Valve For Process Chromatography 8/15/2012

    This case study discusses the need for a fully automated, disposable chromatography system which was PLC controlled and designed for use in a cGMP environment. The required applications for the chromatography system included contamination removal, and concentration and purification of biologically derived proteins used in the production of research and clinical materials. 

58. White Paper: Capillary Electrophoresis — A Simple Technique

    In 1989, Beckman Instruments introduced the first fully automated capillary electrophoresis instrument (P/ACE™ 2000) to the scientific community. At that time, CE demonstrated exceptional resolving of selected compounds, but the new technology lacked a track record of applications. By Beckman Coulter, Inc.

59. 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.

60. 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.
