    摘要: An immunoassay element for quantitatively analyzing a macromolecular antigen by determining the change in enzymatic activity caused by a reaction between the macromolecular polymer antigen and an enzyme-labelled antibody. The immunoassay element comprises a substrate layer containing a non-diffusible substrate which forms a diffusible material in the presence of the enzyme, and a reagent layer containing a fragmenting enzyme for further fragmenting the diffusible material into a lower molecular weight product. Also provided is a process for quantitatively analyzing a macromolecular antigen in a sample by the use of the immunoassay element.

    摘要: The present invention relates to an inhibitor capable of increasing accuracy of the reaction in hybridization, and inhibiting nonspecific hybridization, a clinical diagnostic reagent, and a method of clinical analysis whereby nonspecific hybridization in clinical analysis is inhibited, and a target nucleic substance is detected easily with high accuracy. The inhibitor and the clinical diagnostic reagent contains polymer (H) having a nonspecific hybridization inhibitory action. The polymer has in its molecule at least one of carboxyl and sulfone groups, and phosphorylcholine-like groups, and has a weight average molecular weight of 1000 to 5000000. The method of clinical analysis includes contacting a sample with a test agent capable of hybridizing with a specific nucleic substance in the presence of the inhibitor.
