Description and Uses

TAPS is a zwitterionic buffering agent used in biochemistry and molecular biology. It is part of the Tris family of buffers and is useful for a pH range of 7.7 – 9.1. The members of TRIS family are tris(hydroxymethyl)aminomethane (TRIS), N-[tris(hydroxymethyl)methyl]-2-aminoethanesulfonic acid (TES), N-[tris(hydroxymethyl)methyl]-3-aminopropanesulfonic acid (TAPS), N-[tris(hydroxymethyl)methyl]-3-amino-2-hydroxypropanesulfonic acid (TAPSO), and N-tris(hydroxymethyl)methyl-4-aminobutanesulfonic acid (TABS) buffers[1]. The solubilities of TAPS in aqueous solution decrease with increasing concentration of the salts (salting-out effect)[2]. TAPS is the preferred culture media buffer used for dinoflagellate experiments, allowing for minimal pH change and maximal growth. It is also often used in capillary electrophoresis to analyze DNA and in planar chromatography to separate dyes. TAPS may form a complex with some common metals so stability constants and concentrations should be taken into account when choosing this buffer. TAPS is capable of inhibiting connexin channels in animal cells.
