Call me jaded. One of the latest fads in the production of biologics is “continuous processing.” So let’s concede that the upstream realm can lend itself to continuous processing, but the really hard stuff was always on the downstream side. Here we’ve had to deal with product clarification and purification, which typically involve crossflow (tangential) filtration and chromatography run in a batch mode, with regeneration steps in between whatever was considered a batch…

Mammalian cell culture processes used in the production of monoclonal and recombinant proteins require orthogonal steps in the downstream process to clear virus. Virus filtration is a common, size exclusion-based method in these processes. Initially, tangential flow products were used, but as a result of new-generation virus filtration products, most operations are now constant-pressure, normal-flow operations that can be executed in a single shift operation. The virus filtration step toward the end of the downstream process is now yielding increased protein concentrations…
