Zusammenfassung:LABELED HYDANTOIN CONJUGATE AND ITS USE IN ANALYTICAL ELEMENT AND IMMUNOASSAYS A heterogeneous, competitive binding immunoassay for either phenytoin or phenobarbital is conducted with a labeled conjugate comprising a derivative of hydantoin and a label. The hydantoin derivative is 5-ethyl, 5-phenyl hydantoin and it is linked to the label (e.g. an enzyme) with a linkage derived from an aliphatic monocarboxylic acid. The immunoassay can be carried out either in solution or with a dry analytical element.
