      Q Cellulose resin

      Cat.no : quaternary amine-003C
      Product Overview : Q cellulose strong ion exchangers are highly cross-linked, surface modified media with high dynamic binding capacities and stability at high flow velocities. These high performance optimized media offer significant opportunity for increasing downstream purification throughput.
      Column : 5mm ID ×50 mm L
      Matrix : Highly cross-linked cellulose with dextran scaffold
      Ion exchange capacity : 0.14-0.29 meq/ml‐gel
      Functional group : quaternary amine group: –O–CH2CHOHCH2OCH2CHOHCH2N+(CH3)3
      Protein : quaternary amine
      Average particle size : 40 – 130 μm
      Dynamic binding capacity : 16 mg/mL (BAS); 10 mg/mL (human-γ-globulin)
      Viscosity : Store unopened container at ambient temperature. Do not freeze. Short-term storage for bulk and column (2 weeks or less) can be at a room temperature with pH 2 to pH 13. It is possible to store under alkaline condition at less than 20 °C as recommendation.Longer storage should be in neutral buffer containing 20 % ethanol, at 2 – 8 °C. Do not freeze.
      Chemical stability : Cellulose resin is chemically stable. The media can be washed with a variety of solutions and shows no loss in capacity, resolution or flow rates.
      Physical stability : Cellulose resiin Ion Exchangers are semi-rigid due to the crosslinked structure which gives high mechanical resistance and results in two advantages; no generation of fines during the preparation of the column and higher operating bed height without concern of bed collapse common to many 'soft gels'.
      pH working range : 2-12
      Elution buffer : 0.1 – 2.0 M sodium chloride in adsorption buffer
