Capto Core 700 is a novel, layered bead chromatography resin consisting of a porous outer layer and ligand-activated core. The octylamine ligands found in the core of the beads are multimodal, being both hydrophobic and positively charged. These internalized ligands bind impurities strongly over a wide range of pH and salt concentration. The pores of the bead outer layer prevent large targets (M_r > 700 000) from binding to the ligands while smaller impurities can enter freely into the beads where they are captured.
