Optimizing Feed Strategies with Cellvento® ModiFeed Prime Comp: A Scalable Process

Development of upstream processes, that maximize productivity without increasing complexity, relies on the right combination of medium and feed and the ability to maintain tight control of culture conditions. In fed-batch mode, cells are initially grown in a relatively lean production medium followed by regular feed supplementation to achieve the desired product yield. This App Note presents an optimized feeding strategy and demonstrates how a new, easy-to-hydrate, single-part, pH neutral feed can support optimal cell growth and high productivity of…

Intensifying Upstream Processing and the Implications for Media Management

Process intensification offers many benefits but implementing PI can introduce an unexpected challenge of managing larger media volumes. This whitepaper covers the implications of media management when developing PI strategies. Key Learning Objectives: Gain the tools and knowledge needed to confidently assess intensification options with a focus on media management for new or existing facilities. Follow the media journey from prep to use, exploring potential logistical pitfalls in the management of increased media volumes associated with process intensification. See how…

Intensified Mammalian Cell Culture: Harvest with a Single-Use Hermetic Centrifuge System

The production of increasingly higher cell densities has stressed the already limited solids-handling capabilities for traditional intermittent ejection centrifuge systems. By contrast, a single-use disc-stack centrifuge based on the solids-flow principle offers distinct advantages for cell culture harvesting. Such benefits include solids handling of high-density cell culture processes and elimination of the separation disruption and aerosol generation associated with the intermittent solids ejection. A single-use system also provides well-established benefits of disposable components — such as removal of steam- and…

Ligand Binding Assays: Return on Investment Analysis using Octet®

Octet® systems enable analytical assessment of biologics in various stages of the development workflow beginning with discovery and early selection to validation, manufacturing and quality control. The instrument’s configuration and sample plate format coupled with real-time analysis allows for rapid assay method development. In the last couple of years, Octet® systems have been used by multiple organizations to generate supporting data submitted to various regulatory bodies for the approval of different biologics drug candidates. In addition, Bio-Layer Interferometry (BLI) technology,…

Automation Solutions for the Efficient Integration of Single-Use Equipment

Single-use process technologies have been increasingly incorporated into the manufacturing of biopharmaceutical products over the past two decades. While the reasons for implementing SU systems for biomanufacturing are compelling, there are still some challenges and concerns related to their use. Process automation is often considered one of the weak points of single-use technology. Automation islands are frequent phenomena with SU systems, and integrating the equipment with larger automation systems is challenging. A number of suppliers – like Cytiva, Merck-Millipore, Sartorius,…

Autologous CAR T-Cell Manufacturing Using a Semi-Automatic, Closed, Modular Workflow

There have been tremendous efforts 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 the…

7 Key Questions for Understanding the Benefits of Scale-out Biomanufacturing

Changes in production scale required due to increasing product needs throughout clinical trials introduces risk to the product development timeline. Both the process and the product can be dramatically impacted from scaling-up to larger production volumes due to changes in the bioreactor microenvironment. By “scaling-out,” instead of “scaling-up” these risks can be mitigated. The “scale-out” biomanufacturing paradigm, which involves simply adding one or more of the same-sized bioreactor to the manufacturing run to obtain the production volume required, can also…

Material Transformation in Wet Granulation – The Effect of Continuous Process Dynamics, Material and Formulation Properties

Continuous manufacturing (CM) is increasingly used as an alternative to traditional batch manufacturing of solid pharmaceutical dosage forms. Wet granulation is one of the manufacturing technologies that was successfully migrated from batch to continuous processing. Thereby, the residence time of material under (stress) conditions is significantly reduced which in many cases is a main advantage of CM. However, in other cases with slow transformation processes this raises new challenges. In particular, the question arises as to which process parameters and…

3M™ Harvest RC Chromatographic Clarifier Beta Testing Series Summary

Frost & Sullivan invited a panel of industry leaders and key opinion leaders in pharmaceutical bioprocessing to participate in a new and unique thought leadership forum, the Virtual Think Tank (VTT) Early Access series. Each VTT panel, comprising professionals from pharmaceutical companies, contract development and manufacturing organizations (CDMOs), and 3M Company, discussed the new 3M™ Harvest RC Chromatographic clarification technology following participation in a beta test program that allowed them early access to work with the product and provide hands-on…

Comparison of Gator BLI and Progen ELISA for Quantitation of AAV Serotypes

The determination of total capsid titer is one of the critical quality attributes for AAVs used in gene therapy. This application note presents quantitation of AAV serotype 2, 5, 8 and 9 using GatorPrime™ system and Gator™ AAVX probes, and compares the performance with Progen Xpress ELISA assay for the same serotypes. The Progen ELISA kit is commonly used for AAV quantitation and while it performs well, it has several drawbacks for routine operation, viz, need to dilute the samples…
