The pH dependence is a double sigmoid, consistent with two protonation equilibria in the reductant with pKa values of 2.7 and 5.5, and the reaction rate increases with increasing numbers of negative donor groups in the complex.doi:10.1039/DT9870002485Michael G. Segal...
UsesBIS-Tris Propane is a buffer that is useful in the pH 6.3 - 9.5 range. This wide buffering range is due to its two pKa values, 6.8 (pKa1) and 9.0 (pKa2), being so close. Because of the wide buffering range, particularly down to pH 6 - 7, this buffer has been used to enh...
Tris has a pKa of 8.06 and is very useful in the biology and biochemistry lab because it has buffering capabilities in the range of the typical physiological pH of most living organisms (pH 7.0-9.0). Tris has been reported to interfere with the activity of a number of enzymes, it should...

These obtained pKa values were in good agreement to those obtained by potentiometric titration [17]. The fourth pKa does not seem to have been reported, presumably because it is very low: we found that the chemical shifts did not deviate significantly from those of H3BzTren3+ until ca. pD...
As a commonly used buffer, Tris-HCl buffer solutions are widely used in biochemistry and molecular biology to maintain stable pH values for biomolecules such as nucleic acids and proteins[1]. Tris-HCl and Tris Tris-HCl is an acidic buffer, mainly used to prepare buffers with a physiological ...

BIS-TRIS propane is a zwitterionic buffer with an unusually wide buffering range, from approximately pH 6 to 9.5, because its two pKa values are close in value. BIS-TRIS propane has been used to enhance the stability or activity of restriction enzymes, compared to Tris ...
