Analytical device for detecting analyte in sample, has antibody-immobilized microporous membrane, breadth corner layer of which is attached to semi-rigid liquid-impervious body, and absorbent body, provided separately

摘要

An analytical device (I) for detecting an analyte in a liquid sample, comprises a semi-rigid liquid-impervious support body (SB), a microporous member such as membrane containing multiple immobilized antibody spots attached at the lower surface towards the top breadth side with water-insoluble adhesive over SB, and a body of absorbent material capable of absorbing liquid, provided separately. An analytical device (I) for performing immunoassay for the detection of analyte in a liquid sample, comprises a reaction membrane which is liquid-permeable and porous and having an upper and lower surface, where an exposed area of the upper surface has immobilized in it an antibody or antigen capable of binding to the target analyte, where the immobilized antibody or antigen is concentrated in a multiple spotted region of the upper surface, a semi-rigid liquid-impervious bottom support layer, where a portion of lower surface of the reaction membrane in breadth corner having no immobilized antibody or antigen, is attached to upper surface of support layer by water-soluble adhesive or tape having glue on both sides, and a body of absorbent material having an upper surface and lower surface, capable of absorbing liquid, provided separately.
