a technique for the solid-phase conjugation of ferritin to monovalent antibodies ( fab-fragments of immunoglobulin g ) is described in which fab-fragments from sheep antiserum to rabbit fab-fragments are first adsorbed to sepharose containing insolubilized rabbit immunoglobulin g , and subsequently allowed to couple with ferritin previously activated with toluene-2,4-diisocyanate .
