ABSTRACT:
The present invention concerns coupling agents having the following general formula:activated intermediates consisting of a coupling agent such as defined above with either a molecule having on its surface at least one aldehyde and/or ketone function before conjugation, or with one to eight molecules having on their surface at least one free thiol function before conjugation, conjugates consisting of a coupling agent such as defined above, of a molecule having on its surface at least one aldehyde and/or ketone function and of one to eight molecules having on their surface at least one free thiol function, and the use of said conjugates for in vitro diagnostic methods of diseases involving recognition of a ligand-anti-ligand pair.
