With the continuous expansion of the ivd market and in ivd molecular diagnostics industry, we not only provide high-quality raw materials such as CMIT/MIT Preservation, IVD preservatives, monoclonal antibodies, and antigens for the diagnostic industry but also provide IVD test kits like Ebola test kit, HCV test kits, dengue test kit, etc.
Tris HCl is a very important biological buffer, which is widely used in biological system diagnosis industry, such as electrophoresis and protein biotechnology. Tris HCl use has a pKa of 8.1, which makes it very suitable for biologics formulation.
2 amino 2 hydroxymethyl 1 3 propanediol hydrochloride buffer can be used in a variety of biological applications, including medium, electrophoresis separation and diagnostic reagent formulation. It can provide a stable weak alkaline environment (7.0-9.1), and the pH value of all buffers depends on temperature and concentration. For tris hydrochloride buffer, the pH increases by about 0.03 units for every 1℃ increased in temperature and decreases by 0.03-0.05 units for dilute every 10 times.
