PIPES (piperazine-N,N′-bis(2-ethanesulfonic acid)) (Cat No.: R021308) is a zwitterionic buffering agent commonly used in biological and biochemical research. It maintains stable pH in the range of 6.1 to 7.5, making it ideal for experiments involving proteins, enzymes, and cells. PIPES is valued for its minimal interference with metal ions and biochemical reactions. It is particularly used in cell culture media, electrophoresis, and microscopy. Due to its low UV absorbance, PIPES is also suitable for spectrophotometric assays and optical applications in research.
