Bis-Tris propane buffer, also known as BTP, is a zwitterionic biochemical buffer used for pH adjustment in various laboratory applications, particularly molecular biology, biochemistry, and electrophoresis. Its wide buffering range, from pH 6.3 to 9.5, is attributed to its close pKa values of 6.8 (pKa1) and 9.0 (pKa2). This broad buffering range allows it to maintain stable pH conditions in a variety of experiments.
Furthermore, Bis-Tris propane is a water-soluble buffer that plays a crucial role in improving the stability and activity of restriction enzymes. Specifically, its buffering capacity is advantageous for experiments requiring pH levels as low as 6-7. Tris buffers are insufficient at pH below 7.5 and exhibit significant pKa fluctuations with temperature changes; Bis-Tris propane is a better alternative in this regard. Additionally, it can be used in conjunction with hydrochloric acid buffer to stabilize farnesyl diphosphate, particularly during its isolation from Saccharomyces cerevisiae. In particular, it can act as a ligand and form binuclear hydroxyl complexes with lanthanide (III) rare earth elements.
