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, especially for RNA agarose gel electrophoresis, where it helps maintain the integrity of RNA molecules by providing a stable pH environment. MOPS buffer is also utilized in cell culture applications to maintain physiological pH levels, ensuring optimal growth conditions for cells. Additionally, it is employed in protein purification processes and enzyme assays, where precise pH control is crucial for accurate results. Its compatibility with many biochemical reactions makes it a versatile choice for researchers in maintaining consistent experimental conditions.
