The Uses of MOPSO sodium salt
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.
