Large Pore Size 300nm Q PS-DVB Resin

• Alias: LPS; Q; Ion Exchange
• productkeywords: LPS; Large Pore Size 300nm Q PS-DVB Resin; LPS-50V-Q2
• Product Overview: Large Pore Size 50V Q large pore strong anion exchange chromatography medium, using polymer PS-DVB (polystyrene divinylbenzene copolymer) as the matrix, the matrix is made of sugar-containing polymer and polystyrene composite, high mechanical strength, good chemical stability, through a unique hydrophilic modification of the surface, so that its non-specific adsorption is low. And can tolerate high salt loading. The product has the advantages of high flow rate, high load capacity, high alkali resistance and low back pressure through the optimization of medium substrate and ligand density, as well as the design of open super porous structure. Strong anion exchange (Q) chromatography medium was obtained by bonding ion exchange functional groups on the surface of hydrophilic medium with a special surface modification technique.
• Product characteristics: High loading capacity: 3000Å large aperture can make more virus particles enter the packing hole for exchange and combination;
  High yield: It can maintain the structural integrity of macromolecular proteins or viruses, and obtain the target proteins with high yield and high activity;
  High column efficiency: molecular mass transfer speed is fast, protein or virus particles can easily enter the hole to bind;
  High salt tolerance: high salt loading can be tolerated, eliminating the desalting step, simplifying the operation process and reducing costs;
  Flow rate: Fast flow rate, suitable for processing large volume samples in a short time, improve production efficiency.
