REAGENTS AND METHODS FOR THE DETECTION AND QUANTIFICATION OF THYROXINE IN FLUID SAMPLES

摘要

Immunoassay methods and reagents for the specific quantification of thyroxine in a test sample are disclosed employing antibodies prepared with thyroxine derivatives of formula (2) wherein P is an immunogenic carrier material and X is a linking moiety. The present invention also describes the synthesis of unique labelled reagent of formula (4) wherein Q is a detectable moiety and W is a linking moiety, preferably fluorescein or a fluorescein derivative.
