Ion Exchange Resins, Sepabeads Resin Weak Base Methacrylic Anion Exchanger 600A 75-150µm 1.0 meq/ml Chloride Form Water Content: 41-47%

The CQ grade resins are based on a highly crosslinked polymethacrylic matrix, which is further hydroxylated for added hydrophilicity. These matrices are functionalized with either a quaternary amine (trimethyl amine) or a diethyl-aminoethyl to form strong basic and weak basic anion exchangers respectively with a chloride counterion. By varying the bead size of these resins, the chromatographer can control the efficiency and the resolution in the separation of anionic proteins, peptides, and polynucleotides (separation ran at a pH > PI of the target molecule). These methacrylic matrices have excellent mechanical strength with wide range pH stability (1 to 13) and resistance to high temperatures (up to 60°C operating temperature).

The FP grade resins are based on highly crosslinked polymethacrylic matrix, which is hydroxylated for added hydrophilicity. These matrices are functionalized with either a diethyl-amino, or hexyldiamine to form weak basic anion exchangers. These resins are used in the large scale separation of anionic proteins, peptides, and polynucleotides (separation ran at a pH > PI of the target molecule) as well as enzyme immobilization supports. These methacrylic matrices have excellent mechanical strength with wide range pH stability (1 to 13) and resistance to high temperatures (up to 60° C operating temperature). FP-DA13 is a unique product to Mitsubishi Chemical. The diethylamine (DEA) functionality is a secondary amine base group which provides increased capacity towards target molecules.
