1. A method for the determination of one component of an immunological conjugate in a fluid sample comprising the steps of(a) forming an immunological conjugate reaction product including said one component from a fluid sample immunologically bound to its corresponding component, a bound label compound, and a bound lectin, said lectin being bound to said corresponding component,(b) contacting said reaction product with insolubilized sugar selectively and reversibly reactive with said bound lectin to reversibly bind the reaction product through the lectin to the insolubilized sugar,(c) separating the insolubilized sugar-bound lectin product from the remainder of said reaction mixture, and(d) determining the amount of label compound in either said insolubilized sugar-bound lectin product or said remainder as a measure of the quantity of said one component in said sample.
