Continuum Theory of Active Phase Separation in

Dense cellular aggregates are common in biology, ranging from bacterial biofilms to organoids, cell spheroids, and tumors. Their dynamics, driven by intercellular forces, is intrinsically out of equilibrium. Motivated by bacterial colonies as a model system, we present a continuum theory to study dense, active, cellular aggregates. We describe the process of aggregate formation as an active ...

US6365395B1 - Process for removing protein

A process is provided for selectively removing protein aggregates and virus particles from a protein solution in a two-step filtration process. In a first step, a protein solution is filtered by tangential flow filtration through a cellulosic ultrafiltrate membrane at a transmembrane pressure of between about 1 and about 10 psi to produce a first permeate and a retentate stream.
