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.
Claims5
A KL-6 immunoassay reagent comprising a solution at a pH of 4.0 to pH 5.5 containing a rheumatoid factor interference inhibitor and a solution containing an insoluble carrier on which an anti-KL-6 antibody is immobilized.
A KL-6 immunoassay comprising measuring the change in absorbance accompanying the agglutination of an insoluble carrier due to the immune reaction between KL-6 in a 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, using the sample, a rheumatoid factor interference inhibitor, and an insoluble carrier on which an anti-KL-6 antibody is immobilized.
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 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.
