  • Immunological assay method using magnetic particles
    Patent number: 4777145
    Abstract: Immunological fluorometric assay method, wherein an antigen (1) attached to magnetic particles (3) reacts in a liquid with an antibody (2) present in the sample and with an antibody (4) marked with a fluorescent substance. After the reaction, the particles are pulled by means of a magnetic field through a second (6) liquid layer onto the bottom of the measurement vessel, whereupon the particles are excited, and emitted radiation is collected through the wall of the vessel.
