Magnetic Bead Removal Using Microcarrier and Cell Separation System

Inconsistent results and deviation are major issues in cell therapy manufacturing, primarily resulting from historically manual methods, scarcity of proprietary tools, and lack of operator training. With this difficult process also comes another hurdle–time. Providing a safe vein-to-vein transmission is critical when a patient is waiting (in many cases) for lifesaving therapy. How can we bridge the gap between speed, quality, safety, and consistency?

 

Magnetic beads have been the benchmark for cell and gene therapy (CGT), and the FDA holds strict requirements for their removal in CGT processing. Current methods require expensive, complex equipment, costly infrastructure, and highly skilled personnel. Despite specialized training, a single individual still needs to operate the process impeccably each time and avoid risking contamination.

 

blog-inline-12693-600x630Through the Magnetic Bead Removal Using Microcarrier and Cell Separation Study, Entegris’ microcarrier and cell separation system was incorporated into an optimized bioreactor subculturing process to maximize viable cell recovery and obtain a high split ratio between bioreactors during scale-up. At the end of each bioreactor run, a small volume of culture was taken as a representative sample of the entire culture. This sample was processed using the conventional tube method and the yield obtained was considered 100% cell recovery.

 

With customized chamber and mesh sizes (10 - 200 µm), the microcarrier and cell separation system can be used for a wide array of applications such as retaining aggregate cells or microcarrier beads, cell washing, and harvest, all while achieving the same or better performance as alternative separation methods.

 

Our closed microcarrier and cell separation system provides scalability, compatibility with a wide array of microcarriers, and can reduce deviations . Entegris is the only manufacturer of small bags specifically built for cells. By partnering with us, you’ll be able to increase yield, reduce deviations, and avoid the risk of residual beads in your final product.

Minimizing Filter Plugging: A Guide for Biologic Contamination Control Technologies

Within the life sciences industry, controlling biological and micro contaminants in process streams is vital to improving operating efficiency and the enablement of technological advances such as modern drug development and monoclonal antibodies (mAbs). Sterile filtration plays a critical role in protecting vital bioprocesses and is the cornerstone in eliminating contaminants. But what happens when a filter gets plugged and how can you minimize impact on filtration performance?

Entegris and Kuhner Shaker: Orbital Shaken Bioreactors and Single-Use Bags

Entegris is proud to collaborate with Kuhner Shaker in the development of a 2500 L single-use bag that could exceed their complex requirements while meeting their production needs at scale. Delivering a reproducible product every time, with the ability for specialized applications across scales is what Entegris does best, and this joint effort is no exception. Kuhner evaluated several bag designs for robustness in their 30-day shaking process that were not able to meet the requirements. The Entegris design not only met the need for 30 days of use but was still going strong over 100 days of continuous use.
