Transcriptome analysis reveals strategies for CHO cell culture media design and feed-spiking strategy to improve batch culture

When looking at batch vs. fed-batch culture, there are advantages and disadvantages to each, so considering the application is very important. Batch cultures are fairly simple, straightforward and take very little time to set up. However, batch culture typically doesn’t yield high mAb titers, due to nutrient depletion, by-product accumulation and short growth and production phases. So a batch approach may be good for lab-scale processes where product needs to be generated quickly and simply with little optimization. In contrast, with fed-batch culture, feeds are added to replenish nutrients, which increases cell concentrations, process time, and can yield much higher titers. However, fed batch culture also requires more time for optimization and resources to run. So this approach is more beneficial in situations where you would are developing long term processes or scaling up to large-scale production…

Automated integrity analysis of AAV and Adenovirus particles using MiniTEM

This study highlights the possibility of automated viral integrity measurements of Adeno-associated virus (AAV) and Adenovirus particles and underscores the importance of these measurements being performed in on-grid areas with appropriate stain quality. The analysis is performed using MiniTEM-enabled automated imaging, particle detection, classification and quantification. The analysis provides, a metric for determining the proportion of intact or broken particles in virus samples. In addition, as broken AAV particles may occasionally form undesired doublets or triplets, a metric for determining the proportion of such AAV particle formations is also demonstrated…

De-risking early stage clinical trials – an upstream continuous production solution for biologics

In this mini-webinar, Scott Waniger, VP Bioprocessing, Cell Culture Company, presents a cost effective, early stage clinical trial production process. This process utilizes a continuous upstream manufacturing approach, which reduces production time, lowers cost and simplifies scale-up. To begin the webinar, Mr. Waniger describes current challenges in commercial drug manufacturing. With one of the most pressing, being the overall rise in aggregate costs. He explains that the overall cost of commercializing a drug, based on last year’s data is $2.6 billion dollars. This represents a 3 fold increase over just the past 12 years. In addition, these candidates have a high failure rate with only 1 in 10 Phase I drug candidates (1 in 20 for oncology drugs) reaching approval. These high costs coupled with high failure rates represents a huge financial risk for biopharmaceutical companies. As such, decreasing costs associated with clinical trials has been identified as a top priority for many pharmaceutical companies…

Development of DoE based fed-batch strategies for high-producing CHO cell cultures

Successful optimization of Chinese hamster ovary (CHO) cell culture for biomanufacturing has a significant impact on productivity, protein quality, manufacturing efficiency and economic feasibility. To achieve the highest performing cell culture, a fed-batch culture strategy is frequently used. In fed-batch culture, it is important to begin with a robust base media and then add a complimentary feed strategy…

Automated, single-use filtration to increase efficiency in upstream and downstream operations

In examining ways to improve overall bioprocess efficiency, filtration is a step that can sometimes be overlooked. However it is a key area to improve efficiency, as it is part of both upstream and downstream operations and consumes sizeable resources. The application of single-use technologies coupled with increased automation have successfully improved efficiency in other bioprocess operations, thus it is logical that filtration would also benefit from these technologies…

Bioburden Contamination in Downstream Bioprocesses – Potential entry points for contamination and innovative solutions

Bioburden contamination in biopharmaceutical manufacturing is a big concern. Contamination carries both tremendous cost and preventing it requires strict control of several possible entry points. The cost of bioburden contamination for a company can involve lost time, lost material, batch loss, possible facility closure and extensive QA/QC time to ensure proper cleaning and validation. In the worst case scenario, it can prevent supply of much needed medicine to patients and loss of commercial revenue…

Cool Tool – Achieve Integrated and Scalable Continuous Chromatography

Over the last decade, advances in the upstream processing of monoclonal antibodies (mAbs) has resulted in higher bioreactor titers. With increasing titers, the production bottleneck has shifted to downstream processing. Hence, the biopharmaceutical industry has reached a milestone where the need for higher throughput in downstream processing is leading to the adoption of more efficient multi-column continuous (MCC) counter-current chromatography systems which increase overall productivity while significantly reducing consumables costs…
