Corning X-WASH System: DMSO Reduction of Cryopreserved Human Mesenchymal Stem Cells

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…

Financial Benefits of Off-Site Prefabricated Cleanroom Infrastructures

by Maik W. Jornitz

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…

Freeze Cycle Testing of
Fluoropolymer Bottles

by Eric Isberg

Frozen storage of bulk drug substances (BDS), including bioprocess solutions, vaccines, blood components, and other delicate process fluids is common in the bioprocess industry. Vessels used to store those fluids must be capable of withstanding long-term storage in extremely cold temperatures (e.g., –85 °C or –196 °C), sometimes for very long time periods. They also must also maintain integrity after repeated thawing and subsequent refreeze. The study below was performed to characterize performance of fluoropolymer bottles with standard and two-piece…

Autologous CAR T Cell Manufacturing Using a Semiautomatic, Closed, Modular Workflow: Seamless Transition from Discovery to Clinical Manufacturing

by Sean Chang

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,…

Enabling High-Performing
Perfusion Cell Culture

by Benjamin Madsen and Chris Brau

At least one report estimates that by 2025, 35% of biologics will be manufactured using enhanced processes, particularly perfusion-based bioprocessing. Results of two innovations that support this need for enhanced processes are examined below. The Thermo Scientific HyPerforma DynaDrive Single-Use Bioreactor (SUB), the latest advancement in SUB technology, offers better performance than other bioreactors and scalability up to 5,000 L. Gibco High-Intensity Perfusion CHO Medium is formulated to provide exceptional performance and ease of use, with capability of sustaining >1…

The iCapTag Protein Purification Platform: Bridging Research and Manufacturing

by Izabela Gierach and David W. Wood

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…

Design and Performance of a New Single-Use pH Sensor with Long Shelf Life and High Stability

by Ben Arriola and Jinbo Hu

Single-use biopharmaceutical manufacturing systems require gamma-sterilizable, highly stable, accurate, and simple-to-use single-use pH sensors with a long shelf life. Herein we report the design and performance of a single-use pH sensor technology optimized for single-use bag applications such as those found in bioreactor and mixing applications. This technology is the basis of Emerson’s Rosemount 550pH Single-Use Sensor. The sensor is compatible with gamma irradiation and can be attached to a single-use bioreactor bag via industry accepted ports. With the incorporation…
