Summary for Patent: 6,780,978
Title: Fluorescence-activating antisera and IgG fraction therefrom
Abstract:This invention allows the fluorescence analysis of a nonfluorescent dye with high specificity and high sensitivity by virtue of the formation of a complex among an antibody directed against an immunogen having the nonfluorescent dye, an antiserum containing the antibody, and the nonfluorescent dye, which is an IgG fraction of the antibody, as well as, of the manifestation of fluorescent ability of the dye, which would otherwise be nonfluorscent, resulting from the formation of the complex. Also, the invention enables higher sensitivity in fluorescence measurement where the background fluorescence is less, by employing Malachite Green which will turn into a fluorescent dye.
