MOPSO sodium salt Product Description
MOPSO sodium salt, also known as sodium 3-(N-morpholino)propanesulfonate, is a commonly used buffer in biological and biochemical research. It is a white crystalline powder that is very soluble in water. MOPSO sodium salt is often used as a buffer to maintain a stable pH value in various biological experiments and enzymatic reactions. It is especially useful for applications requiring a pH range of 6.5 to 7.9 because of its pKa value of 7.2. This buffer range makes it suitable for cell culture, protein purification, and molecular biology techniques.
In addition to its buffering capacity, MOPSO sodium salt also has the ability to stabilize certain proteins and enzymes, helping to maintain their activity and structure. It is considered a zwitterionic buffer, meaning it can exist in positively and negatively charged forms, depending on the pH of the solution. When using MOPSO sodium salt, it is important to measure and prepare buffer solutions accurately to achieve the desired pH level. A calibrated pH meter or pH indicator is recommended to monitor and adjust the pH accordingly.
Overall, MOPSO sodium salt is a valuable tool in laboratory research, providing a stable pH environment and supporting various biological and biochemical experiments.

| Uses |
MOPSO Sodium is a biological buffer also referred to as a second generation “Good′s” buffer which displays improved solubility compared to traditional “Good′s” buffers. The pKa of MOPSO Sodium is 6.9 which make it an ideal candidate for buffer formulations which require a pH slightly below physiological to maintain a stable environment in solution. MOPSO Sodium is considered to be non-toxic to culture cell lines and provides high-solution clarity.MOPSO Sodium can be used in cell culture media, biopharmaceutical buffer formulations (both upstream and downstream) and diagnostic reagents. MOPSO based buffers have been described for fixation of cells from urine samples. |
