An approach towards surface imprinting using the enzyme ribonuclease A

Abstract

An adsorbent showing enhanced selectivity for the enzyme RNase A was prepared by a surface imprinting procedure based on metal coordination. A metal chelating monomer, N-(4-vinyl)-benzyl iminodiacetic acid, was polymerized onto methacrylate-derivatized silica particles in the presence of RNase A and metal ions. Lysozyme and RNase A were separated on the adsorbent used as stationary phase in high-performance liquid chromatography.
