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® transfection reagents and Ingenio® EZporator® Electroporation System, which are both easy to use and cost-effective.
A single dose of MSC therapy could consist of billions of cells per patient. To sustainably meet this clinical demand, cell expansion processes must be transformed from static cultures to suspension-based systems. This application note describes an efficient approach to process optimization in a scale-down model for suspension-based cell expansion.

While oral administration remains the most popular route for drug delivery, many of the active pharmaceutical ingredients (APIs) in use and development today exhibit low bioavailability, owing to low solubility which leads to a lower passage through the intestinal membrane, a key step to enter the systemic circulation. As such, formulators have developed a toolkit of enabling formulation techniques to increase bioavailability, including solid-state modification, formulation with lipids, salt formation with meglumine and complexation with cyclodextrins. However, the high degree…
Bio-Layer Interferometry (BLI) systems are used throughout biotherapeutic discovery, development, manufacturing and quality control (QC) workflows to simplify and streamline measurement of process and product attributes. They offer an excellent alternative to assays performed using time- and labor-intensive methods such as ELISA and HPLC. These label-free assays can be run fully automated, require much less user intervention, and provide a simplified workflow. Following an introduction to the principles of BLI, we highlight how the Octet® BLI platform has been used…
Risk management and the establishment of a robust mammalian cell line development (CLD) platform is key in the effort to bring biologics into the clinic as quickly as possible while also achieving high productivity and maintaining expected product quality. Utilizing the same mammalian cell platform early in the lead molecule discovery efforts as that used for eventual GMP production provides critical manufacturability and developability data while also delivering consistent cell culture growth characteristics and product quality and titer information to…
In bioreactors, microorganisms or cell cultures produce complex therapeutic proteins and other biopharmaceuticals. The industrial production of those active pharmaceutical ingredients usually involves a seed train: the cells are run through many cultivation systems, which become larger with each passage (Upstream Process). An adequate number of cells for the inoculation of large-scale production bioreactors of 10,000 liters or more is generated. A prominent example from the growing mammalian cell culture processing sector is the upstream production process of monoclonal antibodies.…
Virus filtration is a critical unit operation in recombinant protein purification processes. Process development of virus filtration operations typically strives to maximize filter capacity and improve process robustness. Adsorptive prefilters are often used to remove higher order protein aggregates and improve filter capacity. While adsorptive membrane prefilters offer easy scale up and implementation, their narrow operating window may result in extensive process development screening studies. By contrast, synthetic depth filters offer a wide operating window and the potential for a…
cGMP grade transfection reagents should be produced and formulated following strict guidelines. Some suppliers manufacture transfection reagents according to medical devices cGMP standards which makes the reagents suitable for viral vector manufacturing in the United States but not suitable for direct administration into humans. Those are often labelled as “for research use only and further manufacturing. Not for use in humans or animals”. Others comply to pharmaceuticals cGMP guidelines, making the transfection reagent suitable for viral vector manufacturing as well…
FILTROSPIN™ 20 by FILTROX enables you to quickly and efficiently test different depth filters or quickly purify a small amount of liquid. The filters are inserted into standard 50 mL centrifuge tubes (Labcon® SuperClear® 50 mL tubes). The liquid is then filtered using a centrifuge or vacuum. In order to evaluate the most suitable and optimized production process, small-scale trials are the key factor to start with. With the help of laboratory scale trials, errors and other issues can be…
Pharmaceutical and biopharmaceutical manufacturing relies on the timely and seamless orchestration of many steps to meet aggressive timelines and ensure operational efficiency. A fundamental element of the processing workflow that can impact schedules is the use of multi-ton quantities of bulk raw materials such as buffers, salts and stabilizing chemicals. These raw materials are typically prepared in a just-in-time manner to meet dynamic production needs and enable rapid changeovers.
