The full Chinese name for MOPSO sodium salt is 3- (N-morpholino) propanesulfonic acid sodium salt, which belongs to a type of biological buffer and is mainly used as a buffer solution for regulating pH in biochemical experiments. Its effective buffer range is between 6.5 and 7.9. Speaking of this, I don't know if it reminds you of MOPS buffer. Yes, MOPS sodium salt is actually a derivative of MOPS, so they are extremely similar in terms of name, pH range, and even application. And in some aspects, its usage effect will be better than MOPS. Application of MOPS sodium salt: 1. MOPS sodium salt has almost no permeability to cell membranes and can be used as a cell culture medium; 2. Not complexing with most metal ions, can be used as a buffer in metal ion solutions; 3. As a buffer for RNA separation in agarose gel; 4. Perform protein purification in chromatography.
