Aqueous Two-Phase System (ATPS)

An Aqueous Two-Phase System (ATPS) is a technique used in science and biochemistry to separate different components in a liquid. It consists of two layers of water-based solutions that do not mix well, allowing substances to distribute themselves between the two layers. This method is often used to purify proteins or other biomolecules because it can gently separate them without harsh chemicals. The two layers form due to differences in properties like density and solubility, making it a valuable tool in research and industry for efficient separation processes.
