Principle of magnetically promoted rapid immunofluorescence (MRIF). Round cell (white): normal cell, spindle cell (brown): malignant cell, orange dots: antigens on the malignant cell, plate (light blue): plate slide, black bar: magnet, red y shape: antibody, blue star shape: fluorescence, black dots: ferrite, black arrow: direction of magnetic force. (A) The magnet attracts the beads to the cells and accelerates the binding with fluorescent ferrite (FF) beads and the antigens. (B) Nonspecific adherence is removed by magnetic force.
