PROBLEM TO BE SOLVED: To preserve a solid phase immunological reagent stably for a long term under dry condition without lowering the immunological activity by adding any one of casein, whey protein or a decomposed product of casein into the solid phase immunological reagent. SOLUTION: The solution for stabilizing a solid phase immunological reagent contains casein and/or whey protein or a decomposed product of casein. Casein in milk, includingα-casein,β-casein,γ-casein,κ-casein andλ-casein, is added into the solution for stabilizing the reagent, for example. Concentration of casein is normally in the range of 0.05-3.0w/v%, preferably in the range of 0.2-2.0w/v%. The whey protein includes that in milk. Concentration of whey protein is normally in the range of 0.05-3.0w/v%, preferably in the range of 0.2-1.5w/v%. The decomposed product of casein includes enzyme decomposed casein and acid decomposed casein and the concentration thereof is normally in the range of 0.05-3.0w/v%.
