Continuous Bioprocessing

A Look At Perfusion: The Upstream Continuous Process

Although implementation of continuous manufacturing for biopharmaceuticals is in the early stages, continuous cell culture technology has been around for close to thirty years. Perfusion was initially developed in the late 1980s as a means for increasing protein titers (1). However, high costs driven by media consumption limited widespread commercial adoption. In the same time frame, advances in cell line engineering, media composition, and bioreactor design led to 10-fold increases in titers for batch and fed-batch modes, eliminating the first…

Flexible Automation for Continuous Unit Operations

Continuous processing has the potential to provide significant cost and time savings for biopharmaceutical manufacturing, but that potential can be realized only if appropriate automation solutions are available for continuous flow between disparate upstream and downstream operations. Pall Life Sciences’ Allegro MVP system, a fully automated bioprocessing system designed for use in upstream and downstream single-use processing, enables flexible automation and thus facilitates continuous biopharmaceutical manufacturing. This article presents the results obtained using the Allegro MVP system in combination with…

Deciding on an Integrated Continuous Processing Approach: A Conference Report

Biopharmaceutical manufacturers are increasingly investigating or implementing continuous processes, and industry experts are participating in vibrant and healthy discussions on a wide range of process approaches being adopted. We seem to have entered a phase within the biopharmaceutical industry (which is often described as conservative) of intense bioprocess innovation as manufacturers strive to lower costs and provide agile, responsive supply chains for “drug on demand” continuous manufacturing operations. Senior industry leaders met in Berkeley, CA, in late 2015 at ECI’s…
