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.

Immunological assay method using magnetic particles

Fluorometric immunological assay method in which an antigen is attached onto magnetic particles, which are, for the time of measurement, pulled against the wall of the measurement vessel by means of the magnetic field. The magnetic particles adhering to the vessel walls are irradiated and the resultant emitted fluorescence is measured.
