ASSAY CHIP

摘要

An assay chip efficiently carries out first-reaction through second-reaction processing. An assay chip (10) includes fluidic-channel member (11, 12) composed of a light-transmissive lower member (11) and an upper member (12), forming a fluidic-channel (15) therebetween, and a cover member (13) fitted with the fluidic-channel member (11, 12) from the upper-member-(12)-side thereof. An inlet (12a) for injecting a sample solution into the fluidic-channel (15) and a suction opening (12b) for sucking, from the downstream side, the injected sample solution, both communicating with the fluidic-channel (15), are formed on the upper surface of the upper member (12). A pot (13a) for carrying out predetermined pre-processing on the sample solution, a pot (13b) for first-reaction processing to bind a photoresponsive labeling substance to an analyte in the sample solution, an inlet insertion-hole (13c) for inserting the inlet (12a), and a suction-opening insertion-hole (13d) for inserting the suction opening (12b) are linearly arranged on the upper surface of the cover member (13).
