  • Protein immobilization on chelating resins
    Patent number: 4246350
    Abstract: Proteins such as enzymes are immobilized on macroporous resins having recurring bis-picolylamine, imino diacetate or hydroxyethyl picolylamine chelating sites. Immobilization is carried out by contacting the resin with a multivalent metal ion selected from the transition metals or rare earth metals and adsorbing the protein to the resin. This immobilization technique permits strongly binding protein to a high surface area resin. The protein can be readily removed from the resin by simply flushing the resin with an appropriate solution.
