FORFARANDE FOR ANTIGEN-ANTIKROPP-REAKTIONSANALYS MED ANVENDNING AV PARTIKELAGGREGATION OCH RESISTIV PULSANALYS

摘要

In a mixture of two antibody-coated latex particle suspensions, the particles in each suspension being of a different size, respectively, absence of antigen specific to the antibody in the mixture leaves multiplets only of one and the other sizes of particles. Presence of antigen in the mixture results in large particle/small particle coupling, which is detected by the resistive pulse method and indicates that an antigen-antibody reaction has occurred.
