TES S920 With its structural similarity toTES is a zwitterionic buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is part of the Tris family of buffers and has a pKa that is right at physiological pH (7. 4) at 25C, giving it a useful pH range of 6. 8 8. 2. It is used in various protein assays, in micellar electrokinetic chromatography and in Test Yolk Buffer medium. Like most neutral pH, amine based buffers, TES forms a complex with
