Abstract:
1. A diagnostic device for diseases that can be diagnosed based on the ratio of similar structural proteins, which is characterized in that it comprises a) a first probe-detection marker conjugate which is formed between a kind of probe having identical recognition site for two or more similar structural proteins and a detection marker, and b) two or more kinds of second probe, wherein each second probes recognize specifically each of the similar structural proteins, thereby forming a set of a) and b), each of said second probes being immobilized in spatially separate positions from each other(s), thereby to form a detect zone as a whole, said first probe-detection marker conjugate being provided either by being contained in a separate container or by being applied on a membrane pad such that it is free to migrate with aid of mobile phase, and the ratio of said similar structural proteins being able to be instantly read by simultaneous analysis for the reaction result of said similar structural proteins with said first and second probes, needless to conduct respective determination of the levels of each similar structural proteins in a test sample.
