Downstream Processing White Papers and Case Studies

51. 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.

52. 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.
53. 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.

54. 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

55. Effect Of Sterilization On Mechanical Properties Of Silicone Rubbers 6/18/2013

    Silicone rubber is widely used in the pharmaceutical industry where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products must be sterilized frequently and repeatedly by high level energy and/or chemical vapor in order to eliminate bacterial surface contamination.

56. Optimized Sterile Filtration of Pharmaceutical Solutions 11/12/2015

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

57. 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.

58. 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.

59. 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.

60. Continuous Biomanufacturing: 10 Reasons Sponsors Hesitate

    The industry is abuzz with talk about continuous biomanufacturing (CB), and its virtues have been well described. Here we will look at some of the barriers or concerns perceived to limit its value to the industry. Justified or not, quite a few concerns have been expressed regarding the implementation of this new, rather disruptive technology.
