MES Buffer 0.5M, pH 5.0 pH:6 X-gal (5-Bromo-4-Chloro-3-Indolyl-β-D-Galactopyranoside) is a histochemicalMES Buffer 0. 5M, pH 5. 0, 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
