WebDiafiltration, similar to dialysis, uses a semi-permeable membrane to separate macromolecules from low molecular-weight compounds. Unlike dialysis, which relies on …
WebDiafiltration at higher protein concentrations reduces flux, increasing the need for membrane area but decreasing the required buffer volume. Therefore, there is an optimum protein concentration at which to perform diafiltration where the tradeoff between flux and volume is balanced and the minimum membrane area or process time is achieved. how to set map scale in arcgis proWebView all products.
