も、発光反応を利用した方法がより感度が高い。 There are various methods to quantify minute amounts of substances in living organisms using antigen-antibody reactions, such as fluorescence immunoassay (FIA), radioimmunoassay (RIA), and enzyme immunoassay (EIA). It was used. Among these, RIA, which allows for highly sensitive and quantitative determination, was widely used. However, there are many problems, such as the fact that many of the isotope-labeled compounds are unstable, and that they are difficult to handle and difficult to dispose of due to the danger to the human body and environmental pollution. Therefore, recently, EIA has attracted attention because it has no safety issues, there are no laboratory restrictions, the substances used for measurement are relatively stable and can be stored, and it is relatively easy to operate. In particular, it is a highly sensitive measurement method comparable to RIA in measuring the activity of enzymes used as labels.
That is, with the development of methods that utilize fluorescent reactions and luminescent reactions, even more importance has been placed on them. Among these, methods using luminescent reactions have higher sensitivity.

ANSが残り、この微量に残存するANSのために
酵素活性測定が妨害される。 Conventionally, EIA using luminescence reactions has used luminol, isoluminol, etc. as luminescent substances. On the other hand, biological components are often bound to other proteins, and measurements are often performed after this bond is broken with 8-anilino-1-naphthalenesulfon (ANS). For example, in the EIA of thyroxine T 4 , ANS is used as a TBG (thyroid binding globulin) blocker, but even after repeated washing,
ANS remains, and this small amount of ANS interferes with enzyme activity measurements.

This is a reaction solution containing hydrogen peroxide obtained by. ANS is used as a solution in a neutral or basic buffer, especially a buffer with a pH of about 8 to 9.5, such as a barbiturate buffer, and serum albumin is usually added. Bis(2,4,6-trichlorophenyl)oxalate (TCPO) is preferably used as oxalate, which is used in solution in an organic solvent, for example in ethyl acetate.
