  • $334.98 Model Number IB70145



CAS# 77-86-1

  • For use in biological and electrophoresis buffer systems

IBI Molecular Biology Grade Trishydroxymethylaminomethane (Tris) powder is commonly used in biological and electrophoresis buffer systems including Tris-Acetate-EDTA (TAE), Tris-Boric Acid-EDTA (TBE), Tris-Phosphate-EDTA (TPE), and Tris-Glycine (TG) buffers. The useful buffer range for TRIS of 7 - 9 coincides with the physiological pH typical of most living organisms. This is the reason it is one of the most common buffers used in the biology/biochemistry laboratory. Concentrated stock buffer solutions can be made with IBI molecular biology grade tris powder.

IBI offers Tris powder in numerous sizes such as, 500 g, 1 Kg, and 5 Kg. Certificates of Analysis and specification sheets are easily accessed on this web page, just click on the desired tab above.
