MOPS is used as a biological buffer.


Soluble in water (to approximately 33% w/w - clear, colourless solution).


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. A buffer using MOPS free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa ±1), using about a half-equivalent of NaOH.


A buffer using MOPS sodium salt can be made by mixing equimolar MOPS free acid and MOPS sodium salt solutions to attain a buffer of the desired pH. Titration of a solution of MOPS sodium salt with HCl results in a solution that will contain NaCl, so the ionic strength will be higher than appropriate for some applications. Concentrations higher than 20 mM should not be used with mammalian cell cultures.
