摘要： Provided is a method for measuring pentosidine in a specimen, the measurement method comprising the steps of: degrading the specimen with an amino acid degrading enzyme; contacting the specimen after the degradation step with a protein having activity that oxidatively degrades pentosidine; and detecting change resulting from the contact, wherein the amino acid degrading enzyme and the protein having activity that oxidatively degrades pentosidine are different from each other.
