Immunochromatography assay kit
An immunochromatography assay kit includes a specimen dropping portion to which a specimen is dropped, a conjugate portion to which a labeled antibody having a property of binding to a detection target in the specimen is immobilized, and a plurality of detection portions to which a capture antibody having a property of binding to the detection target is immobilized. The specimen dropping portion, the conjugate portion, and the plurality of detection portions are formed on a porous member. An outer shape of each detection portion is a dot shape.
1 . An immunochromatography assay kit comprising:
a specimen dropping portion;
a conjugate portion on which a labeled antibody having a property of binding to a detection target in the specimen is immobilized; and
a detection portion to which a capture antibody having a property of binding to the detection target is attached,
wherein the specimen dropping portion, the conjugate portion, and the detection portion are formed on a porous member, and
wherein a cross-sectional shape of the detection portion is a recess which includes a bottom surface and opposing wall surfaces on either side of the bottom surface.
2 . An immunochromatography assay kit comprising:
a specimen dropping portion;
a conjugate portion to which a labeled antibody having a property of binding to a detection target in the specimen is attached; and
at least one detection portion to which a capture antibody having a property of binding to the detection target is attached,
wherein the specimen dropping portion, the conjugate portion, and the at least one detection portion are formed on a porous member,
at least one recess is formed in the porous member, and
the at least one detection portion includes a bottom surface of the at least one recess.
