3-(N-Morpholino)-2-hydroxypropanesulfonic acid sodium salt, commonly referred to as MOPS sodium salt, is a highly effective buffering agent widely utilized in biological and biochemical research. This compound is particularly valued for its ability to maintain a stable pH in various laboratory applications, making it an essential component in cell culture, protein purification, and electrophoresis. MOPS is especially effective in the pH range of 6.5 to 7.9, which aligns perfectly with the physiological pH of many biological systems, ensuring optimal conditions for enzyme activity and cellular processes.

In addition to its buffering capabilities, MOPS sodium salt is recognized for its low toxicity and high solubility in aqueous solutions, making it suitable for sensitive biological assays. Researchers often employ MOPS in the formulation of buffers for RNA and DNA electrophoresis, as well as in the preparation of culture media for mammalian cells. Its unique properties not only enhance the reliability of experimental results but also provide a safer alternative compared to other buffering agents. With its proven track record in various applications, MOPS sodium salt is an indispensable tool for professionals in the life sciences.
