Aether Q-650 chromatographic resin is based on polyacrylate; the surface has been modified by hydrophilicity then bonded with strong basic ion-exchange groups. It has high loading capacity, good chemical stability and high mechanical strength, small non-specific adsorption. It features excellent biocompatibility and column bed stability, and can provide faster flow rate. It is especially suitable for large-scale preparation applications, significantly improving the production efficiency of downstream purification process, reducing costs and creating better economic benefits. It is widely used in capture, intermediate purification and final polishing of antibodies, proteins, peptides, nucleic acids (oligonucleotides), viruses, insulins and other biomolecules.
