Eppendorf Planet of Knowledge - A New Dimension

Transferring a biologic candidate from the research and development phase to commercial production usually requires increasing the working volume of the upstream bioprocess. During scale-up, process performance optimized at small scale needs to be reproduced at larger scales, ideally without much need for process optimization at large working volumes. This requires reproducing the quality of the seed culture and the cells’ growth environment across scales.

To streamline scale-up, bioengineers commonly use bioreactors with similar geometries at all scales and keep one or more parameters constant between vessels of different sizes, such as k_La, power input per volume or tip speed. Therefore, to design a scale-up strategy, data on scale-up-relevant engineering parameters need to be available for each bioreactor planned to be used. These parameters include vessel geometries, power numbers, and oxygen transfer capabilities.

In this webinar we showcase scale-up of an antibody production process in CHO cells from bench to pilot/production scale. We discuss strategies to prepare seed cultures of reproducible quality in shake flasks. We demonstrate a new concept for software-aided scale-up strategy design, which considers vessel parameters of differently sized Eppendorf BioBLU^_® Single-Use Vessels and Thermo™ HyPerforma™ Single-Use Bioreactors

Target group:

•  Lab managers and research scientists interested in scaling-up their upstream cell culture bioprocess from bench to pilot/production scale
• Lab managers and research scientists interested in single-use solutions for upstream bioprocessing

Learning objectives:

• Get to know a bioprocess workflow from shaker to pilot scale.
• Discuss scale-up strategies used in cell culture bioprocessing
• Learn, how the scale-up assist software feature of the new BioFlo 720 bioprocess control station can support scale-up strategy design
• See the benefits of scalable single-use bioreactors for cell culture bioprocessing from bench to pilot/production scale

This webinar is part of a virtual event. By attending the live webinar you wil  also have access to the Eppendorf Planet of Knowledge Platform on which more engaging and educational content about bioprocess scale-up will be provided.

Webinars will be available for unlimited on-demand viewing after live event.

Exosomes are a population of naturally occurring mobile, membrane-limited, 30 – 100 nm in diameter, extracellular vesicles containing a large number of proteins, lipids, messenger, and micro-RNAs. It was shown that they play a role in the mediation of intercellular communication, the modulation of immune-regulatory processes, tumor metabolism, and regenerative as well as degenerative processes. In recent years, there is increasing interest in the therapeutic potential of exosomes produced by Mesenchymal Stem Cells (MSCs).

Stirred-tank bioreactors offer the possibility to tightly control and monitor the production of exosomes, as well as the scalability, to produce increasing amounts. However, the cultivation of stem cells in stirred-tank bioreactors requires profound knowledge and precise control of the process.

In our talk, we will highlight the potential and benefits of stirred-tank bioreactors in the cultivation of stem cells for exosome production. We will share our knowledge on how we developed the process in our DASbox® Mini Parallel Bioreactor System and scaled-up the process to 1 L controlled by our newest parallel bioreactor control system, the SciVario® twin.

Target groups:

· Scientists new to the cultivation of stem cells in bioreactors

· Experienced scientists looking for tips and tricks to improve their stem cell culture and EV production processes

Learning Objectives:

1. How to cultivate stem cells in a stirred-tank bioreactor: Learn how to identify the right cultivation method, vessel type, vessel material, and instrument configuration for your specific needs
2. Learn how to define and optimize important parameters to improve culture results – incl. Tips & Tricks
3. Live “Ask the Expert” session – Deepen your knowledge and optimize your process

This webinar is part of a virtual event. With attending the live webinar you will also have access to the Eppendorf Planet of Knowledge Platform on which more engaging and educational content about stem cell bioprocessing will be provided.

Webinars will be available for unlimited on-demand viewing after live event.
