Supplier Qualification and Material Selection – A Case Study of Biopharmaceutical Resin Manufacture

To ensure a safe and continuous supply of life-saving biopharmaceuticals, raw materials for biomanufacturing must be selected carefully and suppliers evaluated with much scrutiny. Several instances of drug shortages as the result of either a raw material shortage or contamination reinforce the need for thorough evaluation. Ensuring a reliable supply and the quality of the materials selected is of paramount importance…

Bioburden Control Strategies for Continuous Downstream Processing

Implementing continuous bioprocessing for biomanufacturing has been increasing in interest. As a result, questions have arisen about the implementation of this strategy for downstream processes. Of particular interest is maintaining a high degree of bioburden control in continuous downstream process. While bioburden control strategies for continuous processing focus on prevention, not unlike batch processing, many want to know if there are specific strategies that should be implemented with continuous bioprocessing that are different than those used in batch processing…

Cool Tool – Innovative sorbents enable a robust and streamlined protein purification process

Monoclonal antibodies have long been purified using a platform approach. This platform mainly consists of three chromatography steps. These include a Protein A based affinity chromatography step followed by polishing steps. The purpose of the affinity chromatography is to capture the mAb, while the polishing steps remove any remaining impurities, such as residual DNA, host cell proteins, viruses and aggregates. There are options in the selected polishing steps, but often they involve cation exchange or hydrophobic interaction. Increasingly membrane chromatography is being used as a polishing step to remove any remaining contaminants…

Optimizing mAb Purification with Highly Selective Mixed-mode Cation Exchange Sorbent

In today’s market, mAbs are produced for several therapeutic applications, yet they are not a homogeneous family of products. Each mAb is unique, based on its isoelectric point, hydrophobicity and ability to aggregate; the contaminant HCP content is also process-dependent. As drug manufacturers seek to produce mAbs for various application, they are also looking to streamline processes for efficiency and quality…

Scalable Protein A Chromatography for High-Throughput Process Development

Process development is a critical part of biomanufacturing, but it can be very time and resource intensive. With recent industry initiatives around speed to market, process development is an area that could really benefit from high throughput solutions. One high-throughput process development tool for chromatography is the use of 96-well plates. These plate platforms permit automated screening of large numbers of conditions very efficiently and use only a small amount of material for testing. This platform is great for screening but requires bridging experiments to translate results to process scale. In addition, automating the 96-well process requires investment in liquid handling equipment in order to reach the full potential of the platform…


Eppendorf Bioprocess Workshop

Implementation of an Affordable and Scalable Manufacturing Strategy for Gene Therapy
Upstream bioprocess development is an integral part of gene therapy product development. Cell culture bioprocess development is usually carried out at small working volumes. This helps save time and resources, because several experiments can be conducted in parallel, costs for media are kept low, and relatively little laboratory space is required. When more material is needed for characterization, trial runs, and finally for commercialization, biopharmaceutical companies transition the process to bench scale and then up to pilot or production scale. In this presentation, we will present bioprocess solutions for parallel process development at small scale. Furthermore, we will discuss bioreactor scalability and address several scaling approaches.

A Beginner’s Guide to Bioprocess Modes – Batch, Fed-Batch, and Continuous Processing
We will discuss the differences between batch, fed-batch, and continuous fermentation and how these influence culture growth. As an example, we look at E. coli fermentation processes at bench scale. We track the biomass and nutrient concentrations during batch, fed-batch, and continuous fermentation runs. We explain different methods to analyze the process, including determination of biomass, growth rate, productivity, yield, and analysis of process costs. The  comparisons can help bioprocess engineers to select the most appropriate method to meet their needs.  In our examples we studied E. coli fermentation at bench scale. The principles may also apply to bioprocesses using other microbes or mammalian cells, at both smaller and larger scales.
