TLDR
In this paper, an immunoassay for detecting protoporphyrins in a biological sample using an antibody to one compound selected from the group consisting of protopmorphyrins is presented.Abstract:
PROBLEM TO BE SOLVED: To provide a method and device capable of noninvasively diagnosing a tumor of the digestive system. SOLUTION: The detection method and device of protoporphyrins in a biological sample comprise an immunoassay for detecting protoporphyrins in a biological sample using an antibody to one compound selected from the group consisting of protoporphyrins. The antibody is fixed at a prescribed position of a membrane carrier to form an uptake site, and protoporphyrins in the biological sample can be detected by an immunochromatography for competitively binding them and labeled protoporphyrins to the uptake site.
