Description

MES monohydrate is a zwitterionic, N-substituted aminosulfonic acid Good’s buffer. This biological buffer is used to attain desired pH concentrations in buffers. It lacks the ability to form a complex with most metal ions, so it is employed as a non-coordinating buffer in solutions with metal ions.

It has been reported that MES monohydrate is used to mimic the acidic tumor microenvironment to observe the effects of acidification on lung cancer cell viability.

USE
MES is a biological buffer often referred to as a “Good’s” buffer .The pKa of MES is 5.96 which makes MES an ideal candidate for cell culture media and protein based buffer formulations to maintain a stable environment in solution. MES is considered to be non-toxic to culture cell lines, highly water soluble and provides high solution clarity. It is used in cell culture media, biopharmaceutical buffer formulations (both upstream and downstream), and diagnostic reagents. MES based buffers are used in purification bioprocesses of antibodies, peptides, proteins, blood components and growth factors.
