[Immunoenzyme test system for the quantitative determination of tetanus antitoxin in vaccinated persons using horseradish peroxidase-conjugated staphylococcal protein A].

An enzyme immunoassay (EIA) system for assays of tetanus antitoxin in vaccinees has been developed. As conjugate, staphylococcal protein A labeled with horse-radish peroxidase is used in this system. The possibility of using the newly developed EIA system in seroepidemiological surveys of the population is shown.
