Abstract

Official abstract text for this publication.

The present invention provides an insulin-specific assay and an assay reagent capable of sensitively and specifically assaying insulin using an antibody having a property of reacting with insulin bound to an anti-insulin antibody while not reacting with insulin not bound to an anti-insulin antibody, without being affected by proinsulin and insulin analogs.

First claim

Opening claim text (preview).

The invention claimed is: 1. An insulin assay method comprising the steps of: contacting a sample containing insulin with a first monoclonal antibody reagent and a second monoclonal antibody reagent, wherein 1) the first monoclonal antibody reagent is the monoclonal antibody 66221, which is produced by a hybridoma which has a depository accession number of FERM BP-11233, and 2) the second monoclonal antibody reagent is the monoclonal antibody 66226, which is produced by a hybridoma that has a depository accession number of FERM BP-11234, and detecting binding of the first monoclonal antibody reagent and the second monoclonal antibody reagent to insulin in the sample and thereby obtaining a measurement value which is dependent on the concentration of insulin in the sample. 2. The insulin assay method of claim 1 , wherein the first monoclonal antibody reagent and the second monoclonal antibody reagent are immobilized to latex particles and insulin is assayed by latex immunoagglutination assay. 3. The insulin assay method of claim 1 , wherein the first monoclonal antibody reagent is immobilized to a solid phase, the second monoclonal antibody reagent is labeled with a labeling material, and insulin is assayed by ELISA. 4. The insulin assay method of claim 1 , wherein the first monoclonal antibody reagent is labeled with a labeling material, the second monoclonal antibody reagent is immobilized to a solid phase, and insulin is assayed by immunochromatography.
