| Research Abstract |
A strong and long-lived chemiluminescence was observed when quinone was mixed with dithiothreitol (DTT) and luminol, and the chemiluminescence intensity was proportional to the concentration of quinone. Therefore, we considered that quinone-labeled antibody could be applied to develop a non-enzymatic chemiluminescence immunoassay. In this study, quinone-labeled antibody was prepared by coupling of 1,4-dihydro-1,4-dioxo-3-methyl-2-naphthylmethyl chloroformate to amino group of antibody. Since the quinone-labeled antibody emitted chemiluminescence after addition of DTT and luminol, it should become a new analytical tool for various substances based on antigen-antibody interaction.
