Bis-Tris Propane 99.0% CAS: 64431-96-5 1,3-bis(tris(hydroxymethyl)methylamino)propaneBis-tris propane, or 1,3-bis(tris(hydroxymethyl)methylamino)propane, is a chemical substance that is used in buffer solutions. It is a white to off-white crystalline powder that is soluble in water. It has a wide buffering range, from 6 to 9.5 due to its two pKa values which are close in value. This buffer is primarily used in biochemistry and molecular biology.

98% DTT CAS:27565-41-9 1,4-DithiothreitolDithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland's reagent.[2] DTT's formula is C4H10O2S2 and the chemical structure of one of its enantiomers in its reduced form is shown on the right; its oxidized form is a disulfide bonded 6-membered ring (shown below). The reagent is commonly used in its racemic form, as both enantiomers are reactive.
