The experimental jig and punch picture of MRIF. (A) The handle is used to adjust the distance between the sample and magnet, which can be adjusted to any distance. (B) Scheme of MRIF. Brown liquid: antibody-coated FF beads, blue liquid: phosphate buffered saline (PBS). (1) Drops of diluted FF beads, (2) the slide is vigorously agitated manually above the magnet on the specimen stage of the jig, (3) brief washing with PBS using a disposable pipette, and (4) the slide is inserted into a plastic container and “washed” with a magnet. Abbreviation: FF, fluorescent ferrite; MRIF, magnetically promoted rapid immunofluorescence.
