Novel single-use valve design increases efficiency and decreases risk of contamination

Risk of contamination and cross-contamination have always been and continue to be big concerns. A recent application note, “Rationale Design of Valves for Flexible Processing” discusses an area of contamination risk that has not seen significant improvements – soft parts, specifically diaphragm valves. The application note states “according to an industry survey, soft parts (valve diaphragms, o-rings, gaskets) are the number one process equipment contamination risk which can lead to batch contamination or loss. On top of that the change out of soft parts represents 50% of overall maintenance time underlining the need for solutions in this domain.” Authors went on to describe the current challenges with traditional diaphragm valves and present a single-use direct replacement alternative that increases efficiency and reduces contamination risk…

Innovative Chemicals for Process Intensification in Cell Culture Media

L-Tyrosine is a key amino acid for both cellular metabolism and protein synthesis and its depletion in fed-batch processes has been correlated with a drop in specific productivity1 and with protein sequence variants.2 This critical amino acid presents an extremely low solubility, especially at neutral pH.3,4 The use of tyrosine di-sodium salt concentrations above 1 g/L in feeds induces precipitation and increases the risk of media instability, mainly through co-precipitation of other amino acids. This may lead to sub-optimal performance due to insufficient supply of nutrients and finally to low performing processes…

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…

Utilizing High-Throughput Process Development Tools to Create a Purification Process for a Biosimilar Molecule

Biosimilar molecules have some unique manufacturing requirements that must be taken into account when planning process development. The requirements for process development typically require a good deal of selectivity, cost-efficiency and the need to meet aggressive timelines. These lend themselves to a process development approach that incorporates high throughput…

“The vaccine against HPV, introduced in 2006, appears to be very successful in preventing cancer in real-world circumstances. HPV, or human papilloma virus, is a common sexually transmitted disease, and while most cases are harmless, some types of the virus can cause genital warts and cancer. Researchers reviewed 40 studies of HPV infection in 14 high-income countries, with data from more than 60 million people followed for up to eight years after vaccination. The study is in The Lancet. They found that the prevalence of HPV 16 and 18, which cause most cases of cervical cancer, decreased over the period by 83 percent among girls ages 13 to 19, and by 66 percent among women 20 to 24. Infection with three other high-risk types, 31, 33 and 45, decreased 54 percent among girls 13 to 19…”
