Immunochromato device and method for measuring samples using the same
First Claim
1. An immunochromatographic device for detecting or measuring a plurality of types of target substances contained in a liquid sample, the immunochromatographic device comprising:
- a sample application section;
a determination section; and
a capillary-flow section, wherein;
the sample application section, the determination section and the capillary-flow section are located so that the liquid sample introduced to the sample application section is transferred to the determination section via the capillary-flow section, the determination section has an immobilization section including one type of first antibody specifically reacting with all the plurality of types of target substances, or a plurality of types of first antibodies each specifically reacting with a corresponding type of target substance, the one type of first antibody or the plurality of types of first antibodies being immobilized, the sample application section or the capillary-flow section has a plurality of types of second antibodies each specifically reacting with all the plurality of types of target substances or a corresponding type of target substance, wherein the plurality of types of second antibodies can be eluted, at least one type of second antibody specifically reacts with one type of target substance among the plurality of types of target substances, and the plurality of types of second antibodies are labeled with different labeling substances.

Abstract
An immunochromatographic device includes a sample application section; a determination section; and a capillary-flow section. The determination section has an immobilization section including one type of first antibody specifically reacting with all the types of target substances, or a plurality of types of first antibodies each specifically reacting with a corresponding type of target substance, the one type of first antibody or the plurality of types of first antibodies being immobilized. The sample application section or the capillary-flow section has a plurality of types of second antibodies each specifically reacting with all the types of target substances or a corresponding type of target substance. The plurality of types of second antibodies can be eluted. At least one type of second antibody specifically reacts with one type of target substance among the plurality of types of target substances. The plurality of types of second antibodies are labeled with different labeling substances.
