Abstract
The present invention aims to provide an assay reagent and an assay for accurately measuring KL-6, in particular, an assay reagent and an assay for accurately measuring KL-6 in samples containing a rheumatoid factor and/or a nonspecific substance other than the rheumatoid factor. KL-6 in samples that contain a rheumatoid factor and/or a nonspecific substance other than the rheumatoid factor can be accurately measured using an immunoassay reagent comprising a solution at a pH of 4.0 to 5.5 containing a rheumatoid factor interference inhibitor and a solution of an insoluble carrier on which anti-KL-6 antibodies are immobilized.
Claims7
A KL-6 immunoassay reagent kit;
- comprising:
- a first solution at a pH of 4.0 to pH 5.5 containing a rheumatoid factor interference inhibitor;
- and
- a second solution containing an insoluble carrier on which an anti-KL-6 antibody is immobilized.
A KL-6 immunoassay comprising:
- providing a sample, a rheumatoid factor interference inhibitor, and an insoluble carrier on which an anti-KL-6 antibody is immobilized;
- and
- measuring the change in absorbance accompanying the agglutination of the insoluble carrier due to the immune reaction between KL-6 in the sample and an anti-KL-6 antibody immobilized on the insoluble carrier in a solution at a pH of 4.0 to pH 5.5.
A KL-6 immunoassay comprising:
- adding to a sample a solution at a pH of 4.0 to pH 5.5 containing a rheumatoid factor interference inhibitor and a solution of solution containing an insoluble carrier on which an anti-KL-6 antibody is immobilized;
- and
- measuring the change in absorbance accompanying the agglutination of the insoluble carrier due to the immune reaction between KL-6 in the sample and the anti-KL-6 antibody immobilized on the insoluble carrier.
