WebDiafiltration is a technique that uses ultrafiltration membranes to completely remove, replace, or lower the concentration of salts or solvents from solutions containing proteins, peptides, nucleic acids, and other biomolecules. 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.
