How Pore and Fibrous Interstice Structure Influence Filter Performance

    A common objective in pharmaceutical processing is the removal of solids from fluid suspensions through filtration. The usual purpose is the removal of the solid particles to a specified extent, within a given time interval, at the largest possible throughput. Attainment of those goals is managed by proper selection of filtration conditions: principally an adequate effective filtration area (EFA) as defined by filter porosity and a proper rate of flow as regulated by applied differential pressure (ΔP) over…

Effect of Sterilization on the Mechanical Properties of Silicone Rubbers

    Silicone rubber is widely used in the pharmaceutical industry, where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products are sterilized frequently and repeatedly by high-level energy and/or chemical vapor to eliminate bacterial surface contamination. Such treatments may also affect the molecular structure of silicone rubbers, causing changes in their physical properties and performance. Several studies on this topic have been reported; until now, however, no systematic investigation has been performed on the effect of…

Isolation of Novel High-Osmolarity Resistant CHO DG44 Cells After Suspension of DNA Mismatch Repair

    Recent technological advances in cell line and bioprocess development have driven significant improvements in product titers and enabled scientists to accelerate product development timelines (1). Despite those successes, many limitations in developing cell lines for biotherapeutics remain. One example in fed-batch cultures is an apparent paradox: when cell growth is inhibited by high osmolarity after multiple additions of concentrated nutrients intended to enhance cell growth and protein production. Generation of novel host cells to overcome specific bottlenecks found…

  Small-Scale Fluid Control       Product: Flipper 6650 solenoid valve Applications: Analytical fluid dosing Features: With a pitch of only 4.5 mm, the Flipper 6650 solenoid valve comes in 2/2- and 3/2-way versions that offer performance comparable to 10-mm and 16-mm valves. The media-separated valve is compact and fast-switching, optimized especially for reproducible and precise dosing of aggressive fluids. Because of its compact size, the valve requires smaller internal volume in the connecting plates, thus increasing efficiency of…

Cell Line Development and Engineering Novel Approaches to Improve Speed of Development, Stability, Manufacturability, Quality, and Fundamental Understanding

I BC’s sixth annual Cell Line Development and Engineering conference will deliver 37 presentations in a three-day, single-track format for the most valuable and intensive learning experience you can attend. This program has earned its reputation by attracting thought leaders in industry and academia to collectively examine and provide solutions to the industry’s most daunting challenges. For 2010, we developed an agenda that will help you achieve your ultimate goal of improving quality and understanding of your cell lines while…

Making a Positive Urban Impact

The nonprofit Center of Research Technology and Entrepreneurial Exchange (CORTEX) was formed to facilitate development of two redevelopment areas in St. Louis, MO. Last month, I explained their vision and introduced the participants, along with highlighting an example development on the campus of St. Louis University. This month, I conclude with several more examples. Center For Emerging Technologies The Center for Emerging Technologies in St. Louis is ranked a top-10 business incubation facilities in the United States. In under nine…
