摘要 |
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. |
