Application:
MES Monohydrate (CAS: 145224-94-8) is a biological buffer often referred to as Good's buffer, used in biochemistry and molecular biology that was selected and described by Good et al. It is useful for cell culture media and protein based buffer formulations to maintain a stable environment in solution. It is also used in the purification bioprocesses of antibodies, peptides, proteins, blood components and growth factors. It is a useful resolving agent for very small proteins on bis-tris gels. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. It is a zwitterionic, morpholinic buffer and commonly used for cell culture media, as a running buffer in electrophoresis, and for protein purification in chromatography. It is used in biochemical diagnostic kit, DNA/RNA extraction kit and PCR diagnostic kit.
