Product Description: Bis Tris propane is a zwitterionic buffer primarily used in biochemical and molecular biology research. Its main advantage lies in having two similar pKa values of 6.8 and 9.0, respectively, which gives it a very wide buffering range, approximately between pH 6.3 and 9.5. The pH of this buffer can be as low as 6-7, which makes it more suitable than Tris buffer for improving the stability and activity of restriction endonucleases. The application fields of Bis Tris propane are very extensive. In the study of DNA polymerase fidelity and PCR reactions, it has been used as a buffer with good results. In addition, it has also been used to maintain the stability of purified farnesyl pyrophosphate from mutant brewing yeast, as well as to study enzyme activity in some experiments. In protein research, Bis Tris propane is used for crystallization studies. In other biochemical and molecular biology studies, it is also used as a buffer. Bis Tris propane has excellent thermal stability and can be used at high temperatures. Meanwhile, due to its molecular structure design, Bis Tris propane is not toxic to most biomolecules, making it a very safe buffer. Overall, Bis Tris propane is a very important biological buffer that plays an important role in biochemical and molecular biology research. Its widespread application and unique characteristics make it an indispensable tool in scientific research. more>
