Selecting Cation or Anion Exchange Support

Separation strategy for amphoteric molecules. If the molecule is stable at a pH above its pl, an anion exchange support is used. If the molecule is stable at a pH below its pl, a cation exchange support is used.

Bio-Rex 70 resins are weak cation exchange resins that are used for the purification and fractionation of peptides, proteins, antibiotics, and other cationic molecules. Bio-Rex 70 resins contain carboxylic acid exchange groups on a macroreticular acrylic polymer lattice. The high porosity of the resins allows large protein molecules to penetrate the pores and have access to the exchange sites located throughout the matrix.

Bio-Rex 70 resins are available in both analytical and biotechnology grades. Analytical grade Bio-Rex 70 resin has been exhaustively sized, purified, and converted to make it suitable for accurate, reproducible analytical techniques. Biotechnology grade Bio-Rex 70 resin is an analytical grade resin that has been certified to contain less than 100 microorganisms per gram of resin.

Larger volumes and special packaging for industrial applications are available on request.
