Abstract
The present invention provides a new sensitive direct sandwich assay for determining the presence of COMP in a clinical sample. Two monoclonal antibodies directed against separate antigenic determinants of the COMP molecules are used in the assay. The invention also relates to three particularly advantageous monoclonal antibodies per se that are directed against human COMP. Cell cultures manufacturing these antibodies have been deposited according to the Budapest Treaty at Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, and have been assigned accession numbers DSM ACC2406, DSM ACC2408 and DSM ACC2418, respectively. A diagnostic kit comprising at least two of these monoclonal antibodies also constitute a part of the present invention.
