March 6, 2018
In this podcast, we interviewed Dr. Peter Levison, Senior Marketing Director – Downstream Processing, Pall Life Sciences about the evolution and benefits of continuous biomanufacturing, what implementation looks like today and what still needs to be realized for full industry adoption.

017 - Cell Harvesting – Selecting a technology compatible with cell density and feed turbidity on Cell Culture Dish.

February 1, 2018

In this podcast and accompanying article, we interviewed Silke Bergheim-Pietza, Global Product Manager Depth Filtration, Pall. We discussed challenges faced in the cell harvesting step, in particular, selecting the best cell harvesting method based on the cell density and feed turbidity of the process and meeting the demand of increasing cell densities. Download the cell harvesting technology selection guide and use the guide to compare the latest single-use harvesting technologies.


016 - Addressing Challenges in Downstream Biomanufacturing with a platform purification approach

January 30, 2018

In this podcast, we interviewed Jonathan Royce, Business Leader, Chromatography Resins, GE Healthcare Life Sciences, about the biggest challenges in Downstream biomanufacturing including overcoming bottlenecks, changing antibody structures and bioburden control. Jonathan shared how a purification platform can address some of these issues and discusses purification challenges that still need to be resolved.


015 - Novel technology enables encapsulated cell therapies without triggering fibrosis

December 12, 2017

In this podcast, we interviewed Dr. Paul Wotton, CEO, about Sigilon Therapeutics’ discovery platform. The platform combines cell engineering and biocompatible Afibromer technology to enable cell therapies that do not trigger fibrosis


014 - Protein A Chromatography – A look at where we have been and where we are going

December 6, 2017

In this podcast, we interviewed Jonathan Royce, Business Leader, Chromatography Resins, GE Healthcare Life Sciences, about the evolution of Protein A including the latest developments in Protein A chromatography resins. We also discussed what the future holds for this purification mainstay and how it can continue to address the changing needs of biopharma.


013 - Resolving large scale buffer management challenges

November 28, 2017

In this podcast, we interviewed Joakim Lundvist, Modality Manager, BioProcess™ Hardware, GE Healthcare about large-scale buffer management challenges. Buffer preparation is known to be one of the most resource-intensive activities in biomanufacturing as large volumes of buffers and process liquids are often required.

We examined the biggest challenges in buffer management and explored how technologies like inline conditioning can provide possible solutions.


012 - FBS – It’s not all created equal – what consumers need to know

November 8, 2017

In this podcast, we interviewed Alyssa Master, Ph.D., Senior Manager of Science and Applications, Nucleus Biologics about some of the challenges of working with FBS, why not all FBS is created equal and suggestions for FBS customers who are trying to navigate these issues.

We began the interview by discussing what FBS is and how it differs from other types of serum. Alyssa explained that FBS is a bi-product of the meat and dairy industry and it is great for in vitro cell growth because it contains a cocktail of growth factors. FBS is biochemically different from other sera like adult bovine serum or even newborn calf serum. Due to these biochemical differences, FBS has become the gold standard and as a result it is more expensive.

Alyssa continued that because of its ability to support cells in vitro it is widely used throughout academia, biotech, large pharma and bioproduction, particularly in cell therapy and vaccine biomanufacturing. I asked why so many use FBS and Alyssa said that it works well for most lines and is readily available. Because it is animal derived, it already contains cytokines and growth factors in the right combination to support cell growth.

011 - Do you have to sacrifice antibody titer for quality? Employing cell biology to get the best of both worlds

October 24, 2017

In this podcast, we interviewed Dr. Adam Elhofy, Ph.D., Chief Scientific Officer, Bio-Ess, about the relationship between antibody titer and product quality attributes such as glycosylation. Dr. Elhofy shares his thoughts on both challenges and opportunities for optimizing both high titer and glycosylation profiles.
