Abstract
Reagents for the detection of specific reactants, such as antigens in biological fluids, comprising a polymer coupled to an antibody, the polymer having a plurality of dye molecules coupled thereto. The reagent is prepared by covalently linking an end functional group of polymers such as polyethylene amine to an antibody, typically through an aldehyde linkage, the polymer molecule having had a plurality of dye molecules, coupled to the polymer through side reactive sites.
