Acidum 4-morpholinoethanesulfonicum MES, puritatis 99%, cum CAS 4432-31-9
Acidum 4-morpholineethanesulfonicum est tampon amphotericum, quod efficax est in ambitu pH 5.5-7.7. Ut tampon, MES late adhibetur in mediis culturae plantarum, solutionibus reagentium, et experimentis physiologicis ad valorem pH temperandum. Detergentiam magnam, dispersionem saponis calcici excellentem, et resistentiam aquae durae habet.
