MES Buffer 30mM, pH 6.5

MES Buffer 30mM, pH 6.5MES, also referred to as 4 Morpholineethanesulfonic acid, is a zwitterionic buffer primarily used as a running buffer for resolving very small proteins on bis tris gels. MES is often known as one of the original Good's buffers. MES solution has a pKa value near physiological pH, it is not absorbed through cell membranes, and it is essentially transparent to UV light. Also used in cation exchange chromatography and as a biological buffer in plant cell
