The amount of enzyme is determined by reacting an enzyme to be measured with a synthetic substrate having at least one structure to be specifically contacted with the enzyme and at least one spectral sensitizer structure, bringing either the reaction product having the spectral sensitizer structure or the unreacted synthetic substrate into contact with a silver halide emulsion layer, exposing the same to light of a spectral sensitizing wavelength region corresponding to the spectral sensitizer structure, developing the silver halide, and then measuring the optical density of developed silver and/or colored dye.
酶量的测定方法是:将待测酶与具有至少一种与酶特异性接触的结构和至少一种光谱增感剂结构的合成底物反应,使具有光谱增感剂结构的反应产物或未反应的合成底物与卤化银乳剂层接触,将其暴露于与光谱增感剂结构相对应的光谱增感波长区域的光下,显影卤化银,然后测量显影银和/或有色染料的光密度。
