Abstract

PROBLEM TO BE SOLVED: To measure an antigen adhering to a carrier present in a liquid, by conducting immunoassay with the use of the carrier, an antibody to an antigen to be measured or its antigen-coupled fragment. SOLUTION: For example, an equal amount of human serum albumin (HSA) as a carrier and Hanganvitziu-Deicher(HD) antigen are mixed and left one day, thereby to form a standard substance. Meanwhile, a Fab fragment obtained by decomposing an anti HD antigen monoclonal antibody with papain is turned to a solid phase. Then, the standard substance and many samples of urine collected from healthy people and patients of various cancers are added to a Fab solid phase well, and reacted. After cleaning, a peroxidase marker anti HSA antibody is added to the samples and reacted, to which a color-producing reagent is further added. An absorbance is then measured. An HD antigen-HSA complex is measured by the obtained working curve. In this manner, cancers, particularly, cancers of urinary organs can be detected at a high rate.

DISCLOSURE OF THE INVENTION As a result of earnest research, the present inventors have found that HD antigen exists in urine, but it exists in the presence of albumin in urine. As described above, since the HD antigen exists in the urine in a state of being attached to albumin, when the ordinary sandwich method using anti-HD antibody is performed, when the lower antibody binds to HD, the upper antibody causes steric hindrance by albumin. Therefore, it cannot bind to the HD antigen. Therefore, antigens attached to carrier substances such as proteins cannot be measured by conventional sandwich methods. In addition, since two antibodies cannot bind to the antigen, it is not possible to perform an immunoassay by the latex agglutination method or the immunoturbidimetric method.

The immunoassay in the method of the present invention can be carried out, for example, by the sandwich method. In the sandwich method, one of the above-mentioned anti-carrier antibody and anti-measurement antigen antibody is used as the lower antibody, and the other is used as the upper antibody.
Either may be used as the lower antibody. In the sandwich method, the lower antibody is first immobilized on a carrier such as a well of a microtiter plate. After washing, blocking is performed with proteins such as casein, bovine serum albumin or skim milk to prevent non-specific adsorption. After washing, a sample is added and an antigen-antibody reaction is performed. After washing, an upper antibody is added and an antigen-antibody reaction is performed. The upper antibody is labeled, and after washing, the label is measured. Alternatively, the labeled antibody is further reacted with the upper antibody to measure the label. The label is an enzyme label (ELI

In the above method, when preparing a calibration curve, an attachment complex of a carrier substance and an antigen to be measured is prepared as a standard substance. For this, a liquid containing a known concentration of a carrier substance and a liquid containing a known concentration of an antigen to be measured are mixed and, for example, at 2 ° C to 8 ° C overnight or overnight, or at room temperature or 30 ° C to 37 ° C 1 to 10 ° C. It can be prepared by leaving it for a time (preferably 1 to 2 hours).

In the conventional sandwich method, since both the upper antibody and the lower antibody were anti-measurement antigen antibodies, the upper antibody could not bind to the measurement antigen due to the carrier substance, and therefore the antigen to be measured should be measured. I couldn't. On the other hand, since the method of the present invention uses the anti-measurement antigen antibody and the anti-carrier antibody as the lower antibody and the upper antibody, it is possible to reliably sandwich the adhesion complex consisting of the carrier substance and the antigen to be measured,
Therefore, the antigen to be measured can be reliably measured.

The immunoassay can be carried out by the latex agglutination method or the immunoturbidimetric method other than the sandwich method. In the latex agglutination method, latex particles are reacted with a sample obtained by immobilizing the above-mentioned anti-carrier antibody and anti-measurement antigen antibody, and aggregation is measured. The anti-carrier antibody and the anti-measurement antigen antibody may be immobilized on a single particle, or may be immobilized on separate particles, and these may be mixed and used. Aggregation can be measured by visual judgment or turbidity measurement with a turbidimeter. Similarly, in the immunoturbidimetric method, the antigen to be measured can be measured by reacting the anti-carrier antibody and the anti-measurement antigen antibody with a sample and measuring the turbidity. The latex agglutination method and the immunoturbidimetric method itself are well known in the field of immunoassay.
