FILM FOR ENZYME IMMUNOASSAY SENSOR

摘要

PURPOSE:To make it possible to measure enzyme reaction which is generated at the same time as an electrode current by fixing an antigen or an antibody to a polytyramine film. CONSTITUTION:Alkali-methanol solution incorporating tyramine is used, and oxidation polymerization is performed. Thus a polytyramine film is electrodeposited on an electrode. Thus an enzyme immunoassay electrode having excellent high sensitivity is obtained. In this polytyramine acting film, the amino acid of a functional group which is liable to bond to an antigen or an antibody is present at a rate of one amino acid per one molecule of tyramine. Orientation is provided for the antigen or the antibody required as the immunoassay electrode. Bonding and fixing can be performed advantageously for immunoreaction at a high density in high efficiency.
