Abstract
A method for immunoassay for an antigen involves the following steps: reacting a sample possibly containing an antigen to be determined, a definite amount of a conjugate of the antigen and a charged substance and a definite amount of labeled antibody specific for antigen; allowing the reaction products to electrophoretically migrate towards a carrier bearing an attached antibody specific for the charged substance, so that when the reaction products contact the carrier any reaction product of labeled antibody and antigen passes through the carrier and any reaction product of the labeled antibody and conjugate binds to the carrier attached antibody specific for the charged substance; determining the amount of labeled antibody thereby bound to the carrier and relating the determined amount of labeled antibody to the amount of antigen in the sample.
