Zhao G, Chasteen ND: Oxidation of Good's buffers by hydrogen peroxide. Anal Biochem. 2006 Feb 15;349(2):262-7. Epub 2005 Oct 25.
It is found that H (2) O (2) oxidizes both morpholine ring-containing buffers (e.g., Mops, Mes) and piperazine ring-containing zwitterionic buffers (e.g., Pipes, Hepes, and Epps) to produce their corresponding N-oxide forms. |

Other neutral pH, amine-based buffers, such as Mops (3-[N-morpholino] propanesulfonic acid), Hepes (N-[2-hydroxyethyl] piperazine-N'-[2-ethanesulfonic acid]), Bes (N,N-bis [2-hydroxyethyl]-2-aminoethanesulfonic acid), Tes (N-tris [hydroxymethyl] methyl-2-aminoethanesulfonic acid), and tricine (N-tris [hydroxymethyl] methylglycine) also form complexes with DNA, giving distorted peaks in the electropherograms. |
