removal of unwanted small molecules
dialysis (biochemistry)









































in biochemistry, 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 macromolecules such as proteins, dna, or polysaccharides. dialysis is also commonly used for buffer exchange and drug binding studies.

"kt"/"v" has been criticized because quite high levels can be achieved, particularly in smaller patients, during relatively short dialysis sessions. this is especially true for small people, where "adequate" levels of kt/v often can be achieved over 2 to 2.5 hours. one important part of dialysis adequacy has to do with adequate removal of salt and water, and also of solutes other than urea, especially larger molecular weight substances and phosphorus. phosphorus and similar molecular weights remain elusive to filtration of any degree. a number of studies suggest that a longer amount of time on dialysis, or more frequent dialysis sessions, lead to better results. there have been various alternative methods of measuring dialysis adequacy, most of which have proposed some number based on kt/v and number of dialysis sessions per week, e.g., the standardized kt/v, or simply number of dialysis sessions per week squared multiplied by the hours on dialysis per session; e.g. the hemodialysis product by scribner and oreopoulos it is not practical to give long dialysis sessions (greater than 4.5 hours) 3x/week in a dialysis center during the day. longer sessions can be practically delivered if dialysis is done at home. most experience has been gained with such long dialysis sessions given at night. some centers are offering every-other-night or 3x/week nocturnal dialysis. the benefits of giving more frequent dialysis sessions is also an area of active study, and new easy-to-use machines are permitting easier use of home dialysis, where 2–3+ hour sessions can be given 4–7 days per week.
