Description

MOPS is a morpholino propanesulfonic acid, a structural analog to MES, the ethanesulfonic acid (first introduced by Good et al.) Both series of buffers were developed to meet the following criteria: midrange pK_a, maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK_a with temperature chemically and enzymatically stable, minimal absorption in visible or UV spectral range, and reasonably easily synthesized. pK_a=7.2 at 25°C, Effective buffering range.
