MOPSO Na is a biological buffer commonly used in scientific research experiments. Its pH usage range is 6.2-7.6. Compared with the commonly used buffering agents HEPES and Tris HCl in living organisms, MOPSO Na has some advantages. Buffering capacity: MOPSO Na has a more stable buffering capacity, making it less prone to pH fluctuations during the reaction process. Ionic strength: MOPSO Na has a lower ionic strength and does not affect the function of many enzymes and proteins. Protection of biomolecules: MOPSO Na has a good protective effect on many important biomolecules, such as DNA, RNA, and enzymes. Avoidance of interaction: MOPSO-Na will not interact with some commonly used gel blockers, dyes and metal ions. Overall, MOPSO Na is a high-quality biological buffer suitable for various biological experiments.
