| Application: | 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. MES 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. |
