Scheme of magnetic bead-based PHAIA. Magnetic beads coated with antibody are placed in the wells of microtiter plates. A constant amount of phage solution and various concentrations of 3-PBA standard solutions are added into the wells. Unbound phage and analyte are washed away with the aid of a magnetic extractor. Bound phages are detected with anti-phage MAb-HRP.
