Downstream Processing White Papers and Case Studies

31. 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.

32. 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.

33. Top 10 Considerations When Selecting An Isolator Supplier

    While price is certainly an important reason for buying any piece of capital equipment, it is not always the top reason. There are important considerations to examine when selecting an isolator supplier.

34. The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems

    Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.

35. Comparing The Automated Pipetting To Volumetric Glassware And Air Displacement Pipettes

    Analytical sample preparation is used in many industries such as forensics, environmental chemistry, mining, beer and wine fermentation and many others. Concentrated samples are diluted and analyzed via High Performance Liquid Chromatography, Gas Chromatography, Atomic Absorption, and/or Inductively Coupled Plasma Spectroscopy to name a few. Traditionally these samples are prepared using volumetric glassware, syringes and/or pipettes.

36. Materials Of Construction For Biopharmaceutical Water Systems 1/15/2013

    Stainless steels are uniquely qualified for bioprocessing applications not only because of their long service life, availability, and fabricability, but also because they are non-corroding, non-contaminant, can be polished to very smooth finishes, are strong and rigid, can withstand heat and chemical sterilization treatments, and are easily welded. By Michelle M. Gonzalez

37. 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.

38. 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.
39. Global Biochemical Profiling For Bioprocess Optimization 6/12/2013

    It is widely understood that the production phase of bioprocessing can have a significant impact on the overall profitability of the biopharmaceutical.

40. Automation Of A Homogeneous Proximity Assay For Detection Of Residual Protein A In Biological Therapeutics

    Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients.
