CM Cellulose resin

Cat.no: carboxy methyl-003C
Product Overview: CM Cellulose resin is designed for the cation exchange chromatography of basic proteins and other biomolecules.
Form: suspension in 20 % EtOH
Column: 5mm ID ×50 mm L
Matrix: Spherical, Cross-linked Cellulose Beads
Ion exchange capacity: 0.09-0.12 meq/ml‐gel
Functional group: carboxy methyl group: –O–CH2COO–
Protein: carboxy methyl
Average particle size: 45 μm-130 μm
Ligand concentration: 0.07-0.14 meq / ml-gel
Dynamic binding capacity: 130 mg/mL (Lysozyme); 58 mg/mL (human-γ-globulin)
Viscosity: Store unopened container at ambient temperature. Do not freeze.Short term (2 weeks or less), bulk and column can be stored at a room temperature with 0.05 M NaOH. Longer storage should be in neutral buffer containing 0.02 % sodium azide or 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: 2-13
Elution buffer: 0.1 – 2.0 M sodium chloride in adsorption buffer
Shelf life: 5 years from date of manufacture
Warning: Avoid sunlight, heat, Oxidizers, acids and alkalis.
