Immunoassay reagents by which an ultraminor constituent (for example, an antigen or an antibody) contained in a specimen can be assayed at a high sensitivity without requiring any operation for separating, for example, immunologically reacted components from unreacted ones, or while simplifying such an operation. These immunoassay reagents aim at quantitating an antigen or an antibody to be assayed in a specimen and contain an insoluble support carrying an antibody or an antigen against the above-mentioned antigen or antibody and an enzyme, an enzyme inhibitor inhibiting the activity of the above enzyme, and a substrate of the above enzyme. |
