TRIS(Tris(Hydroxymethyl)Aminomethane), Bis-Tris, Tricine, TES, TAPS are buffers commonly used in biochemical experiments and molecular biology experiments, and they all contain the structure of TRIS. Then what are the differences in application between these buffers?

We hope that the following table could solve your doubts.

Table 1. The application of TRIS, Bis-Tris, Tricine, TES, TAPS

In specific use, buffers containing the TRIS (CAS：77-86-1) structure will form a strong or weak complex with a variety of metal ions, so the stability constant should be taken into account. In addition, the buffer range and the appropriate type of experiment also should be considered in order to obtain the best experimental results.
