Stabilizing method for immuno active substances immobilized on insoluble carrier and its use in preparation of reagent for measuring physiologically active substances

摘要

An immuno active substance immobilized on a carrier and stabilized by immersing the carrier in a solution of at least one of sugars and proteins can be used for measuring a physiologically active substance even after stored for a long period of time. A preferred embodiment of the invention uses a synergistic mixture of a sugar and a protein as the stabilizing agents.
