New antibodies directed against a haptenic group containing a choline unit, their preparation and their application, and new antigens which make it possible to prepare them

摘要

New antibodies directed against a haptenic group of formula I: -X-CO-O-CH2-CH2-<+>N(CH3)3 in which X represents an optionally substituted alkyl group having 2 to 8 carbon atoms, it being possible for the free end of X in the formula I to contain a functional group such as a -CO- or -NH- group; their preparation and antigens which make it possible to prepare them. Application to the detection and/or to the assay of choline esters using immunochemical or immunocytochemical techniques. <IMAGE>
