In article <322DF927.7352 at ibex.ca>, achim at ibex.ca says...
>I am looking for the temperature coefficient(s) [dpKa/dT] of the
>'bis-tris-propane' = 1,3-bis[tris(hydroxymethyl)methylamino]propane
>for some enzyme kinetic experiments.
>According to the supplier (Sigma) it has the pKa-values:
>pKa1=6.8 and pKa2=9.0 at T=25C.
>Sigma doesn't know the dpKa/dT-value(s) either.
>Can anybody help ?
I found the following information in a booklet from Calbiochem:
pKa 1 = 6.8 at 20 C, dpKa/C = -0.016
