As the SARS-CoV-2 pandemic has spread around the world, scientists, doctors, clinicians and biopharmaceutical companies are working hard to find effective therapies for COVID-19 disease. Approved and investigational medications with a spectrum of activities are being examined as to whether they can be repurposed for COVID-19 and vaccines are being researched and tested for rapid delivery. Due to the magnitude of the effort by all involved, it is difficult to keep track of the numerous therapeutic, discovery and manufacturing related resources available.
We have created this page to house articles that Cell Culture Dish publishes related to Covid-19 and links to resources from suppliers who have gathered information, technologies and techniques that could be helpful for those engaged in Covid-19 related research and manufacturing.

Attendees will get a critical look at the vaccine industry today, its globalization and how the cost of a vaccine is assessed. Different types of vaccine production processes, equipment, and activities will be reviewed with examples from influenza and inactivated polio vaccine manufacturing. Upstream cell expansion and antigen production, and downstream chromatography, inactivation, and formulation and filling will be explored. Strategies and philosophies for process optimization, safety, and quality—including the importance of QbD and final product sterility assurance and delivery—will also be studied.

Demystifying the FBS Selection Process – A guide for evaluating product quality, origination and cost consideration
In this podcast, we talked with Chris Scanlon, Global Marketing Development Manager at Thermo Fisher Scientific about how to effectively evaluate which FBS product is right for each application. This includes weighing product quality levels and country of origin. Chris also shares strategies for maximizing purchasing options and new FBS products on the horizon…
In this guest article from Pall Biotech the challenges of vaccine development and how they can be overcome by applying a quality by design (QbD) platform approach from early process development phases forward are explored. The impact of the COVID-19 pandemic on vaccine production is evaluated, with insight on how flexible, integrated, closed-system processing is advancing the future of safe and efficacious vaccine production….
Benzonase® endonuclease has been used in biopharmaceutical production for DNA removal for over 30 years. It is a genetically engineered endonuclease, from Serratia marcescens, which can completely hydrolyze all forms of DNA and RNA (single-stranded, double-stranded, linear, and circular) into smaller oligonucleotides (<6 kDa) with no base preference. The use of Benzonase® endonuclease for downstream virus purification improving speed of purification, protects the downstream chromatography and filter devices from fouling, and give better product purity and yield while also meeting regulatory requirements…

In this podcast we talked with DQ Wang, PhD, and Vice President, Formulation, Fill and Finish of WuXi Biologics about their DP4 multi-product fill & finish facility featuring the Vanrx SA25 robotic, gloveless, isolator-based filling system. The system significantly reduces drug product fill risk and provides greater aseptic assurance. The facility is the first in China to use this technology platform and the system fits perfectly with “scale-out” manufacturing paradigms. This highly-flexible platform can easily transition between various Container Closure Systems (CCS) such as vials, pre-filled syringes and cartridges including the new Ready-To-Use (RTU) formats…
Combining Ion Exchange and Reverse Phase Chromatography for Highly Efficient and Cost Effective Peptide Purification
Therapeutic peptide purification can be very challenging because of the similarities between peptides and their impurities. There is not a significant difference in retention for the target peptide and a peptide contaminant that has one amino acid that is different. Thus, separation of peptides from by-products requires long retention times that are inefficient. In addition, even small changes in the mobile phase composition can cause significant effects. One way to increase the separating power of RP-HPLC is to make use of an ion-pairing agent, which couples with basic amino acids, resulting in a net zero charge. Generating a net zero charge status enables separation using a reverse phase process. However, the duel reverse phase process can be cost prohibitive for peptides that require a high level of purity…
Increasing upstream titers, the need to increase throughput of existing facilities and the desire to reduce costs are just a few of the drivers forcing paradigm shifts in monoclonal antibody (mAb) downstream processes. These drivers are acutely felt in the selection of chromatography resins, as the purification step is often the source of bottlenecks and is costly…
Cool Tool – Cellulose Fiber-based Chromatography Increases Flexibility and Throughput in Antibody Purification
Recent industry initiatives have put increased emphasis on improving the flexibility and throughput of biomanufacturing processes. To achieve this, new technologies are required that permit faster process times and increased flexibility for a variety of manufacturing scenarios including smaller batch sizes and multi-product facilities. One critical aspect of the biomanufacturing process is downstream chromatography purification and this can often be a time and resource intensive step…
Successful bulk drug substance freeze and thaw is a critical aspect of biologics manufacturing. It is also time consuming and labor intensive. Historically, cryovessels have been the most common technology used for freeze and thaw due to their durability and scalability. However, cryovessels require extensive cleaning processes and infrastructure and labor to maintain them. These challenges, led companies to look for single-use alternatives. While single-use significantly reduces cleaning requirements, they are difficult to scale due to limitations of the size of the bags. Another downside is that they can be prone to integrity issues…
The U.S. government has entered an agreement with life sciences company Cytiva, a unit of Danaher Corp, to expand the manufacturing of products needed to make COVID-19 vaccines, the U.S. Department of Health and Human Services (HHS) said on Tuesday. Under the deal, Cytiva will receive about $31 million to scale up manufacturing of vaccine-related products, including cell cultures and hardware such as bioreactors used for the culturing of cells and antibodies…
Eli Lilly’s late-stage clinical trial of a monoclonal antibody treatment for COVID-19 has been paused by federal regulators due a safety concern, the company said Tuesday. “Safety is of the utmost importance to Lilly.
