MOPSO BUFFER 3-Morpholinoethane Sulphonic Acid

MOPSO is a zwitterionic organic chemical buffering agent; one of Good's buffers. MOPSO and MOPS (3-morpholinopropanesulfonic acid) are chemically similar, differing only in the presence of a hydroxyl group on the C-2 of the propane moiety. It has a useful pH range of 6.5-7.9 in the physiological range, making it useful for cell culture work.
