Leading up to the BioProcess International Event, we'll be highlighting many of the posters you'll be able to find in the hall at the event taking place October 20-23, 2015 in Boston, MA. If you'd like to join us at the event, as a reader of this blog, when you register to join us and mention code BLOG13JP, you'll save 20% off the standard rate! Poster: The Renaissance of Expanded Bed Adsorption?
Presenter: Martin Hoffman, Biotechflow
About: 20 years after development, Expanded Bed Adsorption chromatography fell out of favour in Bioprocessing. Proposed improvements in process efficiency- obtaining high yields from unclarified feed stocks- were compromised by column design and process run failures; in part caused by blocked meshes, lipid breakthrough and demand for high buffer volumes producing high eluting volume. Current media optimize Dynamic Binding Capacity within the expanded bed. Coupled with improved inlet design, increased bed densities are achieved, which permit high flow rates (450 cm/hr) and throughputs. Direct product capture reduces unit costs by 66%, and labour cost and process time. Comparisons with packed bed chromatography result in higher product yield and 43% reduction in buffer volume. Fully-scalable, cGMP EBA column design improvements prevent vortex formation, whilst ultrasound technology enables contactless monitoring of process dynamics and flow rate via feedback to the skid; both factors maximize expanded bed stability. Reduced column footprint and height requirements increase versatility. In recent years, step changes in incubation techniques, media design, column technology and sensor applications have enabled proven improvements in EBA process efficiency and operations. The initial promise may now be considered as surpassed, and a renaissance of Expanded Bed Adsorption Chromatography should be proposed. Can't make it to Boston for the whole event but still want to browse the Exhibit Hall and check out the BPI Innovation Theater? You can join us with an Exhibit Hall and Keynote Pass!
