Scale-Up of Adherent Vero Cells Grown on Cytodex™ Microcarriers Using ReadyToProcess Equipment

In cell culture-based vaccine production, scale-up of adherent cells is challenging. This study shows a process for scaling up adherent Vero cells from static cell factories to influenza production at 50 L scale using WAVE Bioreactor™ systems and ReadyToProcess singleuse equipment. Vero cells were grown to high cell density on Cytodex microcarriers in 10 L working volume. The cells were detached with trypsin and used to seed a 50 L production culture with the same microcarrier concentration. The cells were allowed to reattach and grow on the new microcarriers in a larger Cellbag™ bioreactor chamber. Cells were subsequently infected with influenza virus. The results show a repeatable scaleup procedure.

Purification of Oligonucleotides on TOYOPEARL GigaCap® Q-650S

TOYOPEARL GigaCap Q-650S is capable of delivering oligonucleotides of comparable purity and slightly higher process yields under the same operating conditions to those seen with resins requiring higher operating pressures. This capability allows chromatographers to purify oligonucleotides without the added expense of purchasing high pressure manufacturing equipment.

Overview of a Scale-Up of a Cell-Based Influenza Virus Production Process

The aim of this white paper is to demonstrate how GE Healthcare Life Sciences single-use products can be applied in the field of vaccine manufacturing. A brief discussion around modern vaccine processes is followed by a case study showing the scale-up of upstream and downstream processes for the production of a cell based live attenuated influenza virus using single-use ReadyToProcess technology. Single-use equipment enables quick changeover between products, minimizes risk for cross-contamination between batches, and reduces the need for cleaning and validation operations.

Are You Into Biosimilars?

Polishing of Monoclonal Antibodies Using Capto™ MMC ImpRes in Bind and Elute Mode

GE Healthcare Life Sciences MAb purification toolbox employs protein A chromatography media (resins) such as MabSelect SuRe™ or MabSelect SuRe LX, in the capture step. After the initial protein A step, there is a range of options for intermediate and polishing purification steps. One option is Capto MMC ImpRes, a new chromatographic medium based on a multimodal cation exchange ligand. This work describes a rapid procedure to establish a robust second step in bind/elute mode for the purification of a…

A Short History of Cell Culture Media and the Use of Insulin

A surprising history of cell culture media and the use of insulin, outlining the basic developments behind growing mammalian cells.

It will take you on a journey from the late 1800 where organ tissues were kept in balanced salt solutions -BSS- and later PBS, until the early 50’s synthetic media, over chick embryo extract and Eagle’s Minimal Essential Medium (MEM) or its modification by Dulbecco (DMEM). Finally describing insulin mimicking growth factors.

Gram Scale Antibody Production Using CHO Cell Transient Gene Expression (TGE) via Flow Electroporation

MaxCyte flow electroporation provides a universal means of fully scalable, highly efficient CHO-based TGE for the rapid production of gram to multi-gram level s of antibodies without the need for specialized reagents, expression vectors, or engineered CHO cell lines. In this technical note, we present data demonstrating the reproducibility, scalability, and antibody production capabilities of MaxCyte electroporation. Secreted antibody titers routinely exceed 400 mg/L and can exceed 1gram/L following optimization, thereby enabling multi-gram antibody production from a single, CHO cell transfection. In addition, we present data showing the use of MaxCyte electroporation for the rapid generation of high-yield stable CHO cell lines to bridge the gap between early and late stage antibody development activities.

Has Your Current LIMS Implementation Been a Nightmare?

Because current traditional LIMS have not delivered on their promise, many organizations are still searching for solutions to optimize their laboratory operations. For those engaged in deploying traditional LIMS, frequent sleep-disturbing issues include poor flexibility and configurability, expensive and time-consuming customization, difficulties extending and upgrading systems, poor usability, lack of modular functionality, poor service/support, problems integrating with existing instrumentation/IT systems and extra time and resources required to meet critical qualification/compliance requirements. Learn how you can avoid the top 5 LIMS nightmares and rest easier with today’s next-generation process and execution-centric LIMS.
