PURPOSE:To stably preserve an immobilizing reagent under a dry condition for a long period of time without losing immunochemical activity, by using a stabilizer consisting of water-soluble amino acid or a salt thereof and one or more ammonium salt. CONSTITUTION:A stabilizer of an immobilizing reagent consisting of water-soluble amino acid or a salt thereof and one or more ammonium salt is used. As water-soluble amino acid, neutral amino acid, oxyamino acid, sulfur-containing amino acid, acidic amino acid, basic amino acid and amino acid having a heterocyclic ring etc. are designated and, as a salt thereof, an alkali metal salt is designated. As the ammonium salt, an inorganic ammonium salt and an organic ammonium salt are designated. Further, the above mentioned stabilizer to which bovine serum albumin is added can be used.
