MES is a zwitterionic buffer. One of the "Good" buffers developed for biological applications. It has the advantages of maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range.
A buffer using MES free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa ± 1). Alternatively, volumes of equimolar MES free acid and sodium or potassium MES can be mixed to attain the desired pH.

Glucose oxidase is an FAD-containing glycoprotein. The enzyme is specific for β-D-glucose. O can be replaced by hydrogen acceptors such as 2,6-dichlorophenol indophenol. Glucose oxidase from Aspergillus niger is a dimer consisting of 2 equal subunits with a molecular mass of 80 kDa each. Each subunit contains one flavin adenine dinulceotide moiety and one iron. The enzyme is a glycoprotein containing ~16% neutral sugar and 2% amino sugars. The enzyme also contains 3 cysteine residues and 8 potential sites for N-linked glycosylation. Glucose oxidase is capable of oxidizing D-aldohexoses, monodeoxy-D-glucoses, and methyl-D-glucoses at varying rates. Glucose oxidase does not require any activators, but it is inhibited by Ag+, Hg2+, Cu2+, phenylmercuric acetate, and p-chloromercuribenzoate. It is not inhibited by the nonmetallic SH reagents: N-ethylmaleimide, iodoacetate, and iodoacetamide.
