Resin reagent DEAE

for protein purification

DEAE Focurose HF is a highly pressure-resistant weak anion exchange resin suitable for the separation and purification of all charged biomolecules, such as proteins, peptides, and nucleic acids. It is designed with medium-sized particles and is commonly used for preliminary capture and moderate purification of samples. Features High pressure resistance Maintains high dynamic capacity at high flow rates High chemical tolerance Easy to maintain Performance Parameters High-rigidity agarose Particle size range 45-165µm Average particle size 90±5µm Resin type Weak anion exchange Ion loading 290-350 μmol Cl-/mL resin pH stability 2-9 (operating) / 2-12 (long-term) / 2-14 (short-term) Chemical stability Compatible with common buffer solutions, 1.0 M sodium hydroxide, 8 M urea, 6 M guanidine hydrochloride, and 70% ethanol. Avoid using oxidizing agents and anionic detergents. Linear flow velocity (0.3 MPa) ≥700 cm/h Operating pressure ≤0.5MPa Storage solution 20% ethanol
