Diafiltration exchange factor

WebDiafiltration or DF (sometimes referred to as buffer exchange) involves the addition of buffer such that the liquid surrounding the target is exchanged to one that is preferred for storage stability. Several UF/DF operations can be connected in a series to perform multiple UF/DF steps until the desired purity levels are reached. Webor Buffer Exchange of Biological Samples Diafiltration is a technique that uses ultrafiltration membranes to completely remove, replace, or lower the ...
