Abstract
A process is described for isolating an enzyme-antibody conjugate, wherein the enzyme is horseradish peroxidase or alkaline phosphatase, from an aqueous mixture of said conjugate and unconjugated enzyme. The process involves contacting the mixture with a water insoluble stationary phase having the Ni.sup.+2 ion chelated thereto and binding said conjugate to the stationary phase. The phase containing bound conjugate is then washed to remove unbound enzyme. Thereafter the conjugate is eluted from the stationary phase and recovered in a form substantially free of the unconjugated enzyme.
