What Technologies Should You Apply to Your Vaccine-Specific Process?

Vaccines have been protecting against disease since the late 1700s. They function by triggering the immune system to generate short-term and long-term responses. Because there are many pathogens, there are also many vaccines. They can be classified by antigen character, but the manufacturing flows used to produce them are relatively similar. Read now our Vaccine Bioprocessing Handbook to learn more on similarities and differences on Vaccine processes for: viral vaccines, Virus-Like Particle (VLP) Vaccines, Polysaccharide Conjugated Vaccines, Viral Vector Vaccines…

Early Selection of Optimal Clones Made Easy: A New, High-Throughput, All-in-One Solution for Mannose Glycans Screening and Assessment of Critical Quality Attributes

Glycosylation is a critical quality attribute (CQA) and imparts properties such as stability, folding, solubility, cell-cell interaction and adhesion to proteins. Antibody glycosylation for example is critical due to the role carbohydrates play in modulating effector functions which affect safety and efficacy of therapeutic antibodies. The NEW Octet® GlyM Kit is designed to provide cell line development and upstream bioprocessing Octet® users with a ready to use kit for the rapid screening of % mannose content of purified and cell…

Advantages of Spray-Dried Mannitol in Roll Compaction Processes

Granulation steps as wet granulation are applied before the final step of tableting in order to achieve content uniformity, flowability and compressibility. Wet granulation applies water and therefore needs a drying step. To omit this for reasons of cost and API stability dry granulation or roller compaction is a compromise to achieve the desired content uniformity without having water involved and a subsequent drying step. Studies available in literature mostly focus on the use of MCC and lactose in this…

Is Fiber-Based Protein A Chromatography the Missing Piece in Single-Use mAb Purification?

Protein A chromatography resins are widely used for therapeutic antibody production because they perform well, giving excellent recovery and purity. But resin-based chromatography methods are better suited to large-scale manufacture. In clinical monoclonal antibody (mAb) purification, batch sizes are small, so protein A resins are rarely used to their full lifetime potential. As a result, protein A resins may be cost-prohibitive, especially for mAb manufacturing when doses are very low or where target patient populations are small. Protein A resins…

Setting the Stage for Electronic Data Exchange

Every day, drug manufacturers must consider and address a wide range of challenges and prospects including complex regulatory requirements, intense cost pressures and the business opportunities offered by novel product classes. Transforming biopharmaceutical manufacturing with integration of intensified, continuous, predictive and autonomous operations is one solution that holds promise for streamlining operations, exploring new therapeutic modalities and meeting regulatory expectations which continue to evolve. Digitization and automation, key elements of Bioprocessing 4.0, will be essential for this transformation, in which…

Selecting the Best Transfection Method

When to Use Transfection Reagents, Viral Transduction or Electroporation No single delivery method is ideal for all situations, but researchers may routinely employ a suboptimal approach for the sake of familiarity or to avoid any start-up costs associated with new methods. In this white paper, we will describe three methods (chemical, electroporation and viral transduction) and highlight the Mirus Bio TransIT® and VirusGEN® transfection reagents and Ingenio® EZporator® Electroporation System, which are both easy to use and cost-effective. Additionally, we…

Crude Sample Analysis in Process Development: Time and Cost Savings

This overview highlights a few examples from drug discovery and process development where the Octet® system demonstrated a significant reduction in the analysis time over ELISA and HPLC by eliminating the need for purification, while still achieving high accuracy and precision. The total assay times were dramatically reduced with fewer assay steps and less labor time involved. The easy and versatile, fully integrated Octet® assay has additional advantages over other label-free technologies like SPR, where sample washing steps are required.…

Expanding Applications in Downstream Biologics Characterization: Stability, Formulations and Aggregation Studies using Octet®

Structure is an important characteristic for protein activity and function. Structural alterations due to protein mis-folding, denaturation or unfavorable conditions can lead to the formation of aggregate species that can affect the efficacy and safety of biologic drug candidates. While many biophysical analytical tools are well suited for detecting these aggregates, few offer a combination of structural and functions assessment in the same system. Sartorius’ Octet® platform is an easy-to-use analytical tool that can detect the presence of aggregated species…
