Efficient expression of proteins is an integral part of the biopharmaceutical drug development process. With a range of expression systems, it is important to balance long-term manufacturing goals (e.g., cost of goods and productivity) while matching the expression system to suit the characteristics of a protein (e.g., product quality attributes and long-term stability). Finding the right expression system early on can make or break a therapeutic candidate as it moves from laboratory bench to clinical administration. FUJIFILM Diosynth Biotechnologies has…

Today algae are commercially cultivated for pharmaceuticals, nutraceuticals, cosmetics, and aquaculture purposes. The abundance of vitamins, minerals, and trace elements as well as the fatty acid profile and thickening and stabilizing functions of their polysaccharides make algae valuable. Algae also can be used to produce biodiesel, bioethanol, and biomass that can be burned to generate heat and electricity. Like plants, algae use sunlight during photosynthesis. Photosynthesis is an important biochemical process in which plants, algae, and some bacteria convert the energy…

Many biopharmaceutical manufacturers are implementing single-use containment for transfer of media and buffer materials to prevent feedstock contamination and promote worker safety. But the type of containment system used can have a significant impact on productivity and profitability. Equipment should be evaluated and chosen carefully. Pertinent Questions Systems should be analyzed not only for their basic ability to contain powders of interest, but also for how efficiently they integrate into production process. For instance, could the system introduce productivity bottlenecks,…

The need for a rapid turn-around in quantity (and the loss of technicians in many laboratories) has created a trend toward implementation of single-use vessels. Their advantages include no time lost in cleaning or sterilization (especially for bench-scale, autoclavable systems), no chance of inhibition or cross-contamination due to poor cleaning, and no need for cleaning and sterilization facilities in a crowded laboratory. For production-scale steel bioreactors, fully automated clean-in-place (CIP) and sterilization-in-place (SIP) have been possible for decades. By contrast,…

During the fall of 2014, we received requests from a couple of large, single-use technology (SUT) system integrators asking whether we could develop a new tube clamp for their SUT assemblies and skids. There were several motivating factors behind these requests. As bioreactor skids became larger and larger (with thousand-liter and larger SUT containers), technicians had increasing difficulties assembling current clamps onto tubing. In some cases, technicians were lying on their stomachs and reaching under the bioreactors trying to install…

A finalist for the 2012 BPI Technology of the Decade Award, XCellâ„¢ ATF systems consistently yield high cell retention, concentration, and viability, enabling efficient and productive perfusion and N – 1 perfusion as well as cell banking and seed-train cell culture operations. XCellâ„¢ ATF devices are now available in single-use format, in addition to stainless steel. The new single-use devices deliver 100% cell retention and laboratory-to-production scalability like their stainless steel counterparts but without the need for autoclave sterilization and lengthy…
