Separating molecules in a solution by dialysis is a relatively straightforward process. Other than the sample and dialysate buffer, all that is typically needed is: • Dialysis membrane in an appropriate format (e.g., tubing, cassette, etc.) and molecular weight cut-off (MWCO) • A container to hold the dialysate buffer Webdiafiltration, the concentration of the new buffer salt in the sample will increase at a rate inversely proportional to that of the species being removed. Using continuous … WebDec 21, 2016 · Many scientists still use dialysis for desalting and buffer exchange. Although it’s effective and inexpensive, dialysis can be time consuming and requires large volumes of buffer relative to sample volume.
