Abstract Alternating tangential flow (ATF) filtration has been successfully adopted as a low shear cell separation device in many perfusion‐based processes. The reverse per cycle is used to minimize fouling compared with filtration. Currently, modeling of the ATF system based on empirically derived formulas, leading oversimplification model parameters. In this study, an experimentally validated porous computational fluid dynamic (CFD) was predict localized behavior and pressure profiles...
Tangential flow filtration (TFF) and alternating tangential (ATF) technologies using hollow fiber membranes are commonly utilized in perfusion cell culture for the production of monoclonal antibodies; however, product retention remains a known common problem with these systems. To address this issue, commercially available fibers ranging from several hundred kilo-Daltons (kDa) to 0.65 μm nominal pore size tested all demonstrated undergo moderate severe retention. Further investigation...
Organophosphate pesticides are known to inhibit acetylcholine esterase, an enzyme that degrades at the cholinergic synapse. In this study zebrafish were used understand impact chlorpyrifos, dichlorvos, and diazanon on vertebrate developmental physiology. Pre‐epiboly embryos exposed concentrations ranging from 1μM 1mM. Survival, spontaneous movements, heart rate, swimming behavior, physical abnormalities examined. All three found be toxic developing or above than 100 μM. However, disruption...
