MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers. It is a structural analog to MES. However, MOPS is a more suitable biological buffer than MES because the pH range is closer to pH 7.4.

MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers. Concentrations higher than 20 mM should not be used with mammalian cell cultures.
