Aether SP-650 chromatographic resin is based on polyacrylate; the surface is hydrophilically modified then bonded with strong acidic ion-exchange groups. It has high loading capacity, good chemical stability, high mechanical strength and 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.
