PREPARATION OF VISIBLE COLORED INSOLUBLE CARRIER PARTICLES LABELED WITH A FLUORESCENT DYE AND AN IMMUNOASSAY METHOD USING THE SAME
The object of the present invention is to provide insoluble carrier particles used for high-sensitivity rapid immunoassay, which allow visual observation and high-sensitivity apparatus measurement. The insoluble carrier particles are visible colored insoluble carrier particles labeled with a fluorescent dye, which are used for immunoassay, wherein absorption of fluorescence by the visible colored insoluble carrier particles is low within a wavelength range of fluorescence emitted by the fluorescent dye.
1 .- 7 . (canceled)
8 . An immunoassay method, comprising using visible colored insoluble carrier particles labeled with a fluorescent dye, wherein absorption of fluorescence by the visible colored insoluble carrier particles is low within a wavelength range of fluorescence emitted by the fluorescent dye.
9 . The immunoassay method according to claim 8 , further comprising determining the presence or absence of an antigen-antibody complex by:
allowing the visible colored insoluble carrier particles labeled with the fluorescent dye to bind to an antigen-antibody complex having a target antigen or antibody; and
visually observing coloring of the insoluble carrier particles and/or measuring fluorescence emitted by the insoluble carrier particles.
10 . The immunoassay method according to claim 8 , which is an immunochromatographic method.
