2-[Bis(2-hydroxyethyl)amino]-2-(hydroxymethyl)- 1,3-propanediol, analytical grade, SERVA

Opis towaru

Zwitterionic buffering substance for a pH range of 5.8 – 7.2.
Bis-Tris is used in biochemistry and molecular biology and is a common component of many buffer systems for electrophoresis. Since it may form a complex with some common metals, such as Cu(II) and Pb(II), formation constants should be taken into account when using this buffer in a solution containing metal ions. Bis-Tris is a substitute for the highly toxic buffer cacodylate.
