MOPS buffer is widely used in molecular biology and biochemistry for maintaining stable pH conditions in various experimental procedures. It is particularly effective in electrophoresis, where it helps to separate nucleic acids like RNA and DNA with minimal interference. MOPS buffer is also utilized in cell culture applications to provide a consistent environment for cell growth and maintenance. Additionally, it plays a crucial role in protein purification processes, ensuring that proteins remain stable during extraction and analysis. Its compatibility with many biochemical assays makes it a preferred choice for researchers working on enzyme kinetics and other sensitive experiments.
