Molecular mapping of the immunologic surface of the hCG molecule by monoclonal antibodies (MCA)

Development of 3 different, epitope-selective immunoradiometric assays (IRMA) for measurement of holo-hCG and its free subunits in normal subjects, carcinoma patients and carcinoma cell line cultures

Vermessung der immunologischen Oberfläche des hCG-Moleküls durch monoklonale Antikörper (MCA) —

Entwicklung von 3 verschiedenen epitop-selektiven immunoradiometrischen Assays (IRMA) zur Messung von Holo-hCG und seinen freien Untereinheiten in normalen Individuen, Carcinom-Patienten und Carcinom-Zellkulturen

The 2-site IRMA-design with MCA is demonstrated to be superior over conventional “l-site”-RIA with polyclonal antibodies since it clearly distinguishes different molecular species of a hormone, especially hCG. Such parallel measurements are considered to be of diagnostic value for screening and therapeutic monitoring of tumor patients who produce freeα- and/or freeβ-subunits early in the course of the disease, or exclusively throughout or in addition to holo-hCG.
