Product Description

Applications: IBI Molecular Biology Grade 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.
