General description

BIS-TRIS Propane is Good′s buffer. It acts as ligand and forms series of dinuclear hydroxo complexes with Lanthanides(III) in the pH range 7-9. It is useful for diagnostic assay manufacturing industry.


BIS-TRIS Propane may be used in the following studies:
  • As buffer to investigate the influence of anions with varying nucleophilic properties on the autoxidation of oxymyoglobin (MbO2).
  • Purification of glucose-binding protein from membranes of Sulfolobus solfataricus.
  • As buffer during GeO2 mineralisation.

The archaeon Sulfolobus solfataricus grows optimally at 80 degrees C and pH 2.5 to 3.5 on carbon sources such as yeast extracts, tryptone, and various sugars. Cells rapidly accumulate glucose. This transport activity involves a membrane-bound glucose-binding protein that interacts...

In the presence of a salt in an excess amount, the oxidation of native MbO2 was enhanced considerably above the normal autoxidation in buffr alone with the formation of the corresponding MetMb . anion complex. This anion-induced oxidation of MbO2...
