Dialysis buffer

In chemistry, dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane, such as dialysis tubing. Dialysis is a common laboratory technique that operates on the same principle as medical dialysis. In the context of life science research, the most common application of dialysis is for the removal of unwanted small molecules such as salts, reducing agents, or dyes from larger macromolecul… WebThe dialysis buffer should also be compatible with downstream purification processes, e.g. minimal amount of EDTA or DTT if a HIS Select ® column will be used to remove the cleaved His-tag.
