Traditionally, cell-based vaccine production is performed using stainless steel bioreactors that require extensive cleaning procedures. Because disposable bioreactor systems have no need for cleaning and validation, they can significantly reduce start-up times for good manufacturing practice (GMP) manufacturing of cell-based vaccines (1). Although they are susceptible to a broad range of viruses, Vero cells were recently successfully used for industrial-scale influenza vaccine production (2,3,4). However, these adherent cells can proliferate only when provided with a suitable surface on which to…

Presenting Sustainable Fluid Handling
Picture the scene: You head to the boardroom for a meeting with a vendor who promises to optimize your company’s fluid-handling processes. “Sustainability,” he says, enshrined in the spotlight of an overhead projector, “is at the heart of today’s agenda.” You slump into your chair. Sustainability is key to your business, yet efforts to bottle this elusive ideal have so far cost more than they’ve saved. “How can a sustainable bioprocess container solution enhance my business?” you ask. “It’s about…
The RAMbio Incubator Improves Culture Growth and Protein Expression
End oxygen limitations when growing Escherichia coli, Streptomyces, Pichia, Aspergillus, and other high-demand aerobes in shake flasks. Many bioprocesses rely on aerobic growth and protein expression, yet traditional orbital shakers do not provide adequate oxygen. Cultures become oxygen limited. The RAMbio incubator solves this problem by providing active headspace refreshment using low-frequency acoustic energy that aerates standard shake flasks. Why Use the RAMbio? The increased dissolved oxygen provided by the RAMbio may benefit aerobic microbial cultures by Increasing biomass, protein,…

Validation of the New Single-Use Freeze-Pakâ„¢STS
Figure 1: Production of biologics — whether for clinical development or large-scale manufacturing campaigns intended to be converted to final drug product — often involves frozen storage. It provides manufacturing process flexibility while enabling long-term product stability. Products are frozen and stored using a number of technologies: stainless-steel vessels, bottles, carboys, and disposable bags. Although single-use freezing bags are a common choice for storing biologics, challenges with durability persist. Single-use bags intended for freezing and storage are often made with…
E. coli Cultivation in a 12L and 120L CELL-tainerâ„¢ Single-Use Bioreactor
Although single-use bioreactors are widely applied in the biopharmaceutical industry, microbial cultivation in them is restricted due to limitations in oxygen mass transfer, mixing, and heat transfer. The CELL-tainer™ single-use bioreactor makes use of an innovative principle applying a two-dimensional (2D) rocking motion, thus providing excellent mass transfer, making this single-use reactor very suitable for microbial cultivation at different scales. With a simple pillow-shaped bag without moving parts, the technology is robust and leads to cost savings compared with other…

The…
Cultivation of CHO Suspension Cells and SEAP Expression in the Finesse Glass Bioreactor
This application note describes the cultivation of Chinese hamster ovary (CHO) suspension cells in the Finesse SmartGlass vessel bioreactor with a maximum working volume of 2.0 L. Using chemically defined minimal media, cell densities of up to 7.44 × 106 cells/mL were achieved. Recombinant secreted embryonic alkaline phosphatase (SEAP) expression was induced by medium exchange and temperature shift. Maximum SEAP activities of up to 63 U/mL were reached. A novel stirred glass bioreactor suitable for cell culture applications at benchtop…
Fujifilm Diosynth Biotechnologies
One of the major bottlenecks in the production of biopharmaceuticals is the efficient expression of therapeutic proteins in microbial or mammalian cells. The Escherichia coli pAVEway™ expression system described here has been developed to ensure high product titers and efficient scale up to GMP manufacture while minimizing many common issues seen in other expression systems, such as “leaky” expression (expression of recombinant protein in the absence of inducer). How It Works The use of a number of powerful E. coli…
More Functionality, Lower Costs, Better Usability with the Arc System
Figure 1: Figure 1: When planning a modern 750-L fermentation plant including a cross-flow unit, the GEA Diessel company was looking for the best available measurement technology suited for its customer requirements. Attention turned to the new intelligent Arc sensors from Hamilton. After testing the Arc system, the plant engineer and GEA’s customer were convinced of the advantages of the new technology, deciding to use the Arc system in the fermentation plant. GEA Diessel and Hamilton were able to supply…
