WebHEPES is a similar pH buffering compound that contains a piperazine ring. With a p Ka of 7.20, MOPS is an excellent buffer for many biological systems at near-neutral pH. Applications [ edit] MOPS is frequently used as a buffering agent in biology and biochemistry. It has been tested and recommended for polyacrylamide gel … WebMES buffer gives better separation of proteins at lower molecular weights, while MOPS buffer provides better separation at higher molecular weights (Figure 3). Use MES …

Dr. Norman Good et al. in 1966 described a series of zwitterionic buffers that addressed the above limitations, for research in biology and biochemistry. Typically, these "Good's buffers" have pKa values at or near physiological pH, are non-toxic to cells, and are not absorbed
http://www.whdsbio.com/news/1016.html WebWhich buffer you should use depends entirely on the percentage gel you are working with and what size band (s) you are trying to find. In general, MES will give you larger separation at the lower mass range while MOPS will give you better separation at the higher mass range for your particular gel. Look at invitrogen's precast gels for more info.
