In this case study, process chromatography application scientist Artur Stanczak presents a two-step mAb purification workflow, comparing multimodal resin alternatives used for the polishing step that occurs after protein A capture. The design of experiment (DOE) data presented characterizes the behavior of multiple mAbs with two different mixed-mode resins. The importance of scale, prior knowledge, and the stage of development will also be discussed. The results of both mixed-mode resin studies and the different DOE approaches demonstrate the ability to achieve high-purity products.

Tetanus toxoid (TT) is a common carrier protein for conjugate vaccines, but its production is faced with significant challenges. Learn about a purification process that yields over 98% pure target protein in this video.

Viral clearance studies are part of a multifaceted approach to ensure biopharmaceutical product safety. To prevent costly changes to a manufacturing process, it is important to assess each operation unit for its efficiency early on during downstream process development. See how a design of experiments (DOE) approach was utilized in this case study to investigate the effect of buffer pH and conductivity on the removal of impurities by an anion exchange (AEX) mixed-mode chromatography resin.

Large-scale downstream processing of viruses can face a range of obstacles different from those of many biotherapeutics. These challenges mostly arise from the size and complexity of the virus, which can affect product purity and recovery. Improvements of purification tools are necessary to overcome these challenges and must be engineered for easy scalability to meet manufacturing demands. In this video, Dr. Mark Snyder discusses common difficulties when developing purification strategies for vaccine production and gene therapy.

Learn best practices and guidelines for successfully packing different types of chromatography resins in this video webinar. This includes incompressible resins, like CHT Ceramic Hydroxyapatite Media, as well as traditional compressible resins. In general, parameters such as compression factor, settling rate, and attributes of the base matrix need to be considered when packing resins at process scale. Packing methods can be adapted to obtain simple, highly reproducible packing. Get tips here.

RNA-Seq library preparation is a manually intensive, time-consuming process prone to bias from the multiple enzymes required. So, how can you trust your sequencing results? Bio-Rad is revolutionizing RNA-Seq library prep with the SEQuoia Express Stranded RNA Library Prep Kit – a three-hour, three-tube solution eliminating the need for multiple enzymes and reducing both the number of pipetting steps and protocol time. The key is an engineered, proprietary retrotransposon called SEQzyme. With this serial template jumping, or continuous synthesis, reaction you can obtain an unbiased, stranded RNA-Seq library constructed to accurately represent both messenger and non-coding RNA from your sample.
