His innovative approach has implications for various applications, including affinity chromatography and assay systems.

Latest Patents

James A. Cook holds a patent for the immobilization of biologically active molecules by changing the oxidation state of a transition metal ion. In this process, a chelating agent is covalently bonded to a biologically active molecule, such as an enzyme or antibody. The biologically active molecule is then contacted with a support containing a bound transition metal ion, which is chelated by the chelating agent. The oxidation state of the metal ion is altered through treatment with an oxidizing or reducing agent, resulting in a kinetically inert oxidation state that immobilizes the biologically active molecule on the support. The transition metal ions used in this process include Co(II), Cr(II), or Ru(III), which can be changed to Co(III), Cr(III), or Ru(II), respectively. Various chelating agents, such as iminodiacetic acid and nitrilotriacetic acid, can be employed, and some can immobilize multiple biologically active molecules at a metal ion site.
