IMMUNOASSAY METHOD FOR CORTISOL AND REAGENT USED THEREFOR

摘要

Polyclonal or monoclonal antibodies that specifically recognise cortisol (hydrocortisone) in urine are new, provided that:(a) they are produced by immunising an animal with an immunogen comprising cortisol 3-syn-carboxymethyloxime (I) coupled through the COOH gp. to a macro-mol., or(b) their binding affinity for the histamine conjugate of (I) is ≥ 1 (esp. ≥ 1.5) times their binding affinity for the histamine conjugate of cortisol-3-anti-carboxymethyloxime (II). Also claimed are:(a) (I), (II), their histamine conjugates;(b) a conjugate of (I) and a macro-mol., and(c) the monoclonal antibody produced by hybridoma cell line IMMU-473 (CNCM I-1532).
