General description

3-(N-Morpholino)propanesulfonic acid or MOPS due to its inert nature is a preferred and widely used buffer in many biochemical studies.

Application

MOPS has been used:
  • as a component of Roswell Park Memorial Institute (RPMI) medium for diluting fungal inoculum
  • as a buffer in capillary-zone electrophoresis to test performance
  • for the dilution of proteins from algal samples

Other Notes

Component of running buffer in the fractionation of RNA on formaldehyde agarose gels.
