Figure 1: Observer validation In bioreactor processes, the on-line monitoring of key parameters relies on the use of adequate sensors. In this article, we implement model-based software sensors to monitor nitrate concentrations in an algae batch process. Nitrate concentration is a crucial component in algae growth, and its assessment is used to achieve optimal growth conditions or to determine optimal harvest times. Batch cultivation of the algae Chlamydomonas reinhardtii is carried out in a Labfors 5 airlift photobioreactor provided by INFORS-HT. By means of an extended Kalman–Filter observer scheme, the software sensor is embedded in an eve software platform, which offers a communication structure with the Labfors reactor and enables an operator to implement real-time code for monitoring.

Biopharmaceutical manufacturing is evolving with the progression of Industry 4.0. Industry 4.0 refers to the ongoing “fourth industrial revolution,” which is transforming modern manufacturing and production practices through the use of “smart” technology. This is appealing especially to the biopharmaceutical industry, where production can be a long, meticulous, complex process, and optimizing manufacturing procedures is critical for success. As a leading supplier of single-use technology for the biopharmaceutical industry, PendoTECH recently has explored how its products can be integrated easily with an industrial platform and the opportunities that result. At the heart of the technology that enables PendoTECH sensors and instrumentation to be adapted conveniently to a digital highway is an intelligent automation platform (IAP). Typically, an IAP has analog inputs and digital inputs/outputs for communicating with all unit-operation devices essential to manufacturing (e.g., sensors, transmitters, and monit...

Figure 1: Model clinical virus production is increased in STAT1 KO cell lines with either (left) Influenza A or (right) Dengue II virus. Antiviral vaccines are essential for preventing epidemic disease. However, production of them often is limited by low-yielding manufacturing processes. Similarly, the development of gene therapies is constrained during the production of adenoassociated virus (AAV) delivery platforms for gene transfer. To address the need for efficient viral synthesis to quicken the pace of bioproduction, ATCC used CRISPR/Cas9 genome-editing technology to develop STAT1 and BAX knockout (STAT1 BAX KO) cell lines to produce high-titer viral stocks. Three cell lines optimized for virus production were developed from parental cells commonly used in virus manufacturing. Those newly created cell lines can produce clinical viruses and AAVs at titers that are much higher than those of the parental cell lines, thereby providing an inexpensive method for biopharmaceutical companies to expand produc...

Advancements in life sciences technologies and the increasing demands for improved, effective, and innovative products to prevent, treat, and in some cases, cure diseases have focused the attention of drug developers on new modalities such as mRNA-, DNA-, viral vector-, and cell-based therapies and vaccines. Novel biopharmaceutical products bring a level of complexity to developing and bringing them through design, clinical studies, and to the market. Like traditional drug products, complex therapies require robust, scalable manufacturing processes, a reliable quality-driven supply chain, demonstrable process control, and adherence to regulatory guidelines from upstream through the downstream and fill–finish processes.

Figure 1: Human mesenchymal stem cell (hMSC) viability using an X-WASH system Cryopreservation is a necessary part of workflows for both autologous and allogeneic therapies. The ability to cryopreserve cells for cell therapy increases the range of administration, shelf life, and time for safety testing. Cryoprotectants such as dimethyl sulphoxide (DMSO) often are added to freezing media to increase post-thaw cell survival. However, DMSO itself can be cytotoxic, so reducing its final concentration can be necessary. Below, I demonstrate how the Corning X-WASH system can reduce the amount of DMSO used in cryopreserved cells through a semiautomated, closed system. Using the Corning X-WASH system, we reduced DMSO concentration significantly for cryopreserved bone marrow-derived human mesenchymal stem cells (hMSC) while maintaining high cell recovery and viability.

Traditional cleanroom infrastructures, gypsum, or monolithic wall panels have been used in the past with varying success and benefit. One of the most often proclaimed benefits is the cost of those on-site built structures. Characteristically, the cost quoted at the beginning of a construction project seems to be attractive, but construction estimates are not better than ±50% at feasibility (preconcept) and ±25% at end of conceptual design. Given the above accuracy ranges, industry surveys establish that in most cases, the cost proposal is not met with traditional builds. Those types of cost-control variations cause major problems with budgeting and funding projects. That is because the funding value is either inflated to allow for cost variation (with the risk funding not approved) or another round of funding is needed mid-project. Both are undesirable scenarios. Off-site prefabricated cleanroom infrastructures enable robust cost budgeting because the resource and material loads are well defined and known...

Chimeric antigen receptor (CAR) T cell therapies have advanced rapidly in recent years, with a number of targets in clinical research and several US Food and Drug Administration (FDA)-approved products already on the market. There has been tremendous effort to make CAR T cells more effective, safe, and persistent when treating patients. On the manufacturing side, however, errors, lot-to-lot variation, and contamination can be associated with open processes and manual handling of CAR T cells. Cell isolation, gene editing, expansion, and cryopreservation are complex steps in a typical autologous CAR T cell manufacturing process. Integrating this complicated multistep workflow into a closed, modular, benchtop system can facilitate transitions from laboratory scale to clinical manufacturing and improve a CAR T cell product’s consistency, purity, and safety. Thermo Fisher Scientific presents a digitally compatible, good manufacturing practice (GMP)-compliant, semiautomated manufacturing platform, which when us...

Purification of recombinant proteins remains a critical challenge for applications ranging from basic biological research to the development and production of lifesaving biopharmaceuticals. At laboratory scales, the rapid purification of large numbers of new and uncharacterized protein targets effectively compels the use of affinity tags, which enable reliable purification using simple, established protocols with minimal optimization. Tags cannot be used for therapeutic applications, however, because of their potential for immunogenicity. Thus, for proteins other than monoclonal antibodies (which typically use a protein A affinity platform), biopharmaceutical manufacturing processes must rely on multiple conventional chromatography steps, with six months or longer being spent on developing an acceptable downstream process for a single, well-characterized target. The need for such contrasting approaches has led to the emergence of two worlds in protein purification: one in which affinity tags are used to a...

Raman spectroscopy is used in biomanufacturing as a process analytical technology (PAT) tool for making rapid, nondestructive, in-process measurements. However, Raman data collection at early stages of bioprocess development has been a challenge because of the lack of interface to bioreactors <250 mL. Realizing the industry was struggling to capitalize on the full potential of Raman spectroscopy, Kaiser Optical Systems, Inc. (Kaiser), an Endress+Hauser company, collaborated with Sartorius to bring Raman to Ambr 15 microbioreactors (10–15 mL) and Ambr 250 minibioreactors (100–250 mL). Sartorius’s new BioPAT Spectro platform enables Kaiser Raman–based quality by design (QbD) early in process development and scales up to Biostat STR single-use bioreactors. The following Q&A explains how Kaiser Raman technology and the BioPAT Spectro platform by Sartorius work together to provide biopharmaceutical manufacturers with scalable, real-time bioprocess monitoring.
