Downstream polishing
WebA three-step purification process, with two polishing steps based on one cation exchanger and one anion exchanger, is a classical way of purifying mAbs. Cation exchangers are used for the removal of HCP, protein A, aggregates, and fragments. The cation exchange step is commonly followed by an anion exchange step (run in flow-through mode) for ...

Webbecome an undesirable load to downstream polishing mixed beds. Certain TOC constituents are better rejected at a higher pH. Silica rejection and solubility are higher at elevated pH levels (particularly above pH 9). Boron rejection is higher at elevated pH levels (particularly above a pH of 9). WebMay 27, 2024 · These downstream polishing systems function more effectively at lower concentrations, thereby increasing the contaminant removal rates. In many cases, these filtration systems can be used in a polishing process step, particularly in wastewater treatment applications in commercial or industrial facilities, after clarification of an MBBR ...
The downstream part of a bioprocess refers to the part where the cell mass from the upstream are processed to meet purity and quality requirements. Downstream processing is usually divided into three main sections: cell disruption, a purification section and a polishing section. The volatile products can be separated by distillation of the harvested culture without pre-treatment. Distillation is done at reduced pressure at continuous stills. At reduced pressure, distillation of product dire… WebDownstream processing can be a laborious and costly process, therefore effective and scalable methods of generating high-purity and high yield of AAV particles is critical. ...
