Method for measuring trace enzyme

摘要

In a photochemical measurement methodof a trace enzyme which comprises: using a synthetic substrate bringing either the reaction product formed by enzyme reaction or the unreacted synthetic substrate into contact with silver halide, developing the same, and measuring optical density of the formed silver image and/or colored dye, the synthetic substrate comprises at least one structure (A) which is specifically contacted with an enzyme to be measured and at least one photographically fogging agent structure (B) in the molecule thereof.
