where do we need to use the principle of dialysis
Dialysis (biochemistry) 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 macromolecules such as proteins, DNA, or polysaccharides.[2] Dialysis is also commonly used for buffer exchange and drug binding studies.
