MOPS solution (CAS 1132-61-2)

MOPS solution, a zwitterionic biological buffer, is extensively used in biochemical and molecular biology research for its exceptional buffering capacity in the pH range of 6.5 to 7.9. Its primary utility lies in maintaining pH stability during biochemical reactions, which is crucial for accurate and reproducible results. MOPS is particularly favored in RNA studies because it minimizes RNA degradation, unlike buffers that contain amine groups, which can cleave RNA chains. This makes it an ideal choice for RNA isolation, gel electrophoresis of RNA, and other molecular biology protocols focusing on RNA integrity. In protein research, MOPS is used in protein electrophoresis, including SDS-PAGE, where it serves as a running buffer, ensuring that the pH environment supports protein stability and consistent migration patterns. The buffer is also commonly used in the culturing of mammalian cells and other sensitive biological samples that require a strictly controlled pH environment. Its low ionic strength and minimal interference with biological processes make it suitable for various enzymatic assays, including those that monitor enzyme kinetics and activities within cellular pathways. The versatility of MOPS solution in these research settings underscores its importance in providing a stable and conducive environment for the study of complex biological systems.
