Cell counting and viability assessment are routine but essential parts of bioprocessing procedures, and accuracy, reproducibility, and standardization are essential to successful outcomes. Traditional methods produce variable results because they rely on subjective discrimination of dye-stained cells using a hemacytometer and microscope. Substantial operator-to-operator variability in the cell counts is common, even when one researcher examines the same sample twice. Guava technologies offers a solution: a simple, accurate, and reproducible absolute cell counting and viability assay that overcomes many of…

Figure 1. Developed in 1996, the WAVE Bioreactor™ and Cellbag™ disposable bioreactor systems have revolutionized cell culture for commercial and R&D applications in the production of cell-derived products using animal, insect, plant, microbial, and virus cultures. Oxygen transfer and mixing are accomplished by the novel principle of wave-induced agitation. Wave action generates free surfaces for bubble-free oxygen transfer from the headspace of each Cellbag bioreactor, and it also mixes the fluid suspending cells or particles. This design eliminates the need…

Improving production quality, efficiency, and yield is the objective of every commercial biotechnology process. Automation of assay tasks now routinely performed manually directly improves production bioprocesses. The US FDA supports and encourages this activity through the process analytical technology (PAT) initiative within its regulatory structure. The features and benefits of the online series of Automated Reactor Sampling (ARS-M™) systems supplied by Groton Biosystems are detailed here. Online Automatic Assays Today the most vital late-stage and production assay measurements — with…

Figure 1. There are a variety of affinity tag-protein strategies, and the use of affinity tags depends on the target protein, the expression system, and the application. The Octet QK and Octet RED systems provide an easy-to-use, label-free, high-throughput system to capture affinity-tagged biologics for quantitative or kinetic biomolecular interaction analysis. Kinetic characterization of biologics during clone selection, screening, and development is critical at all stages of therapeutic engineering and bioprocessing. Key Applications Quantitative kinetic characterization (kobs′ ka′ kd′ KD…

Figure 1. On-line biomass monitoring using capacitance is now a routine task in cell culture. The capability to develop advanced bioprocesses relies on sensitive process monitoring technologies and robust process control strategies. Unlike optical technologies, capacitance is insensitive to dead cells, cells debris, gas bubbles, or other matter in suspension. With its capacitance-based sensor, FOGALE nanotech has supplied many pharma/biotech companies around the globe. The Biomass system is widely recognized as a powerful tool from process development to CGMP production…

Emerging lifestyle diseases and an aging population are creating a number of major health challenges. Over the past few years, the food industry has been more focused on functional foods, those intended to be consumed within the normal diet but containing biologically active components with physiological benefits intended to reduce certain chronic diseases. This US$35 billion market has been steadily growing at 8-14% per year, as estimated by the Food and Agriculture Organization of the United States (FAO). Although the…
