DEAE Cellulose resin

Cat.no: diethylaminoethyl-003C
Product Overview: DEAE weak anion exchanger is highly cross-linked, surface modified media with high dynamic binding capacities and stable at high flow velocities. These high performances of the 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: 0.14~0.25meq /ml
Functional group: diethylaminoethyl group:–O–CH2CH2–N+(C2H5)2H
Protein: diethylaminoethyl
Average particle size: 40 μm-130 μm
Dynamic binding capacity: 130 mg/mL (BAS or Lysozyme); 58 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 12. It is possible to store under alkaline condition at less than 20°C as recommendation.0.5M NaOH ; for less than 2 weeks, at 20°CLonger storage should be in neutral buffer containing 20 % ethanol, at 2-25°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.
