PROBLEM TO BE SOLVED: To provide a protein stabilizer that stabilizes a protein in an aqueous solution of a diagnostic-test agent, an enzyme widely used as a pharmaceutical, a recombinant protein, a glycoprotein, a peptide etc., and does not reduce bioactivity of a protein for a long period of time during a production process and a preservation period and to provide a stabilization method. SOLUTION: The stabilizer for a protein-containing aqueous solution comprises a compound (A) represented by the general formula (1) (wherein the organic group X is an ester group or an N-alkylamide group; and the organic group Y is an N-alkanoylamido group or imino group) and/or its salt (B).
