一般描述

TES sodium salt belongs to the category of zwitterionic buffers that contain ionizable groups of both positive and negative charges.[1][2] It has a high water solubility and can effectively stabilize pH levels within the physiological pH range of 6.8 to 8.2 over a broad range of temperatures.[2] TES sodium salt is used in the preparation of electrophoresis buffers.[3] It is one of the commonly used Good buffers[4] in biochemistry and molecular biology research.

Metal-ion affinity (formation) constants were determined for two "Good's" buffers, N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid (TES) and N,N-bis(2-hydroxyethyl)glycine (bicine). The metal chelates formed undergo loss of an internal ligand (alcohol) proton (bicine) and undergo hydrolysis (bicine and TES) and dimerization reactions (TES). Bicine
