Methods for enhancing luminescence of a luciferase (BFP-aq) with fluorescence activity derived from a calcium-binding photoprotein are provided. To a luciferase solution with fluorescence activity that contains an apoprotein, a calcium-binding photoprotein, which is constituted such that a coelenteramide or an analog thereof is coordinated inside, a coelenterazine that is the luminescent substrate of the luciferase or an analog thereof and a compound (e.g., imidazole etc.) having the function of removing an -NH-proton of the pyrazine ring of the imidazopyrazine skeleton in the coelenterazine or the analog thereof are added.
