Upstream Intensification with High-Density Cell Cryopreservation

In all bioprocess stages, developers and manufacturers aim to intensify as many steps as possible. For upstream processes, the result can be significant productivity gains with an evolution of bioreactor train design that takes advantage of higher titers to compress the train and intensify production outputs. Upstream intensification of production-scale bioreactors has driven bioprocess productivity evolution for several years. Interest has been growing in what can be achieved with laboratory-scale cell expansion, which has remained a fairly static process involving…

Easy Perfusion for Anchorage-Dependent Cell Culture Using an Eppendorf Vessel with Microcarrier Spin Filter

Anchorage-dependent cells such as Vero cells are used widely as a platform for viral vaccine production. Perfusion bioprocesses enable a constant addition of nutrients and removal of byproducts while cells are in a bioreactor. That results in cell densities that are higher than those for conventional batch or fed-batch processes. In the study herein, Eppendorf researchers tested the suitability of a spin filter as a cell-retention device. They cultivated Vero cells on Cytodex 3 microcarriers (10 g/L) in an Eppendorf…

Mitigating Raw-Material Risks During a Pandemic

The COVID-19 crisis has reinforced the importance of having a strong supply chain and a risk-management and business-continuity plan. How can you mitigate your raw material risk, especially during a pandemic? Risks When Choosing a Raw Material Supplier: How do you select your critical raw-material suppliers? What selection criteria and which risks have you identified? To understand risks related to supply, demand, material supplier capacities, and so on, you need information that can come only from communicating with your supplier…

Continuous Biomanufacturing Implementation: Using an Intensified and Integrated Bioprocess Platform

Recent world events have demonstrated now more than ever the growing demand for pharmaceutical biologics that can be made rapidly and in high volumes yet somehow remain affordable. Hence, there is an urgent need to develop a next-generation biomanufacturing solution that provides high-yield, high-quality drug products and is highly flexible and cost-effective. Herein we describe the WuXi Biologics ultrahigh productivity platform (WuXiUP), an intensified perfusion culture process developed to meet the aforementioned need. WuXiUP adopts process-intensification strategies on to traditional…

Filtration Solutions for Endotoxin Reduction

PURAFIX ET-R depth-filter sheets are used for efficient and economical reduction of endotoxins from pharmaceutical liquids. Removal of endotoxins is one of the most important and challenging steps in biopharmaceutical processes. Endotoxins — more precisely, lipopolysaccharides (LPS) — are extremely heat and pH stable and therefore withstand sterilization. Purification usually is performed by applying chromatography as a polishing step, which is costly and time consuming. By reducing endotoxin load at an early stage of a clarification process, subsequent purification steps…

Enabling Digital Chromatogram Review for a Faster and More Reliable Operation

Chromatogram review is a monitoring method used to verify process performance in packed-bed chromatography processes. By observing key process parameters such as chromatography column outlet conductivity or UV absorbance, it is possible to identify the signs of a poorly packed column, resin degradation, or equipment malfunction. Therefore, chromatogram review is implemented as an in-process control (IPC) to decrease variability and identify suboptimal performance, thereby enhancing yield and ensuring high product quality.   Fill out the form below to read the…

Integrated Features for Process Intensification

Biopharmaceutical companies are facing major challenges today, including rising drug manufacturing costs and lower production volumes related to unpredictable demands. To achieve the necessary reductions in both costs of goods (CoG) and infrastructure and operational costs, biopharmaceutical manufacturers integrate process intensification strategies into their production schemes. Novasep has embedded specific features into its BioSC™ platform to enable and accelerate process intensification (two key examples being viral inactivation steps management and in-line buffer preparation). BioSC Predict, Exclusive Simulation and Optimization Software:…
