Description
useful pH range 6.5 - 7.9 pKa (25 °C) 7.2 3-(N-Morpholino)propane sulfonic acid (MOPS) is an N-substituted amino sulfonic acid with a morpholinic ring. MOPS is capable of buffering within a pH range of 6.5-7.9. MOPS is widely used in biological and biochemical studies due to its inert properties.It does not interact with any metal ions in solutions and has significant metal-buffer stability especially with copper (Cu), nickel (Ni), manganese (Mn), zinc (Zn), cobalt (Co) ions. MOPS buffer maintains the pH of the mammalian cell culture medium. MOPS functions to maintain pH in denaturing gel electrophoresis of RNA. MOPS can modify lipid interactions and influence the thickness and barrier properties of membranes. MOPS interacts with bovine serum albumin and stabilizes the protein. Hydrogen peroxide oxidizes MOPS slowly to N-oxide form Good's buffer component for biological research Satisfactory for electron transport studies and phosphorylation in chloroplast lamella preparations; non-toxic buffering system for the extensive growth of Streptomyces clavuligerus and cephalosporin production, in a chemically defined medium; electrolyte system component for the IEF of 2-D gel electrophoresis
