High-Performance CM Weak Cation Exchange Resin

• Product Overview: Compared with strong cation-exchange (SP) resins, weak cation-exchange resins offer different selectivity and should be considered when SP resins cannot provide the required selectivity.
  Depending on resolution requirements and application, the CM Weak Cation Exchange Resin series is available in two grades: Fast Flow CM Weak Cation Exchange Resin (~90 μm) and High-Performance CM Weak Cation Exchange Resin (~35 μm). Fast Flow CM Weak Cation Exchange Resin offers fast flow rates for rapid protein purification with broad applicability and easy scale-up. High-Performance CM Weak Cation Exchange Resin delivers high resolution and is mainly used in polishing steps.
