Abstract

The invention relates to a process for the stabilization of biologically active substances which are immobilized on a carrier, where the solid phase with the immobilized biologically active substance is contacted for the stabilization with a solution which contains polyanetholesulfonic acid and/or salts thereof. The biologically active substances are, in particular, antibodies.
