Open the CIPO recordAbstract From the Canadian patent
The invention relates to a process for preparing standards and controls for immunoassays employing monoclonal antibodies. Monoclonal antibodies are used to isolate a restricted portion of an antigen containing an epitope that determines the specifity of the monoclonal antibody-antigen reaction so as to distinguish it from the antigen as a whole following fragmentation of the complex antigen by procedures including proteolysis. Isolated epitopes are attached covalently or by physical adsorption to particles to immobilize and stabilize the epitope. The particles can be composed of iodipamide ethyl ester, polyvinyl chloride polystyrene and other inert substances and can be chemically activated …
