RESUMO

A monospecific antibody against human plasma kallikrein has been prepared in rabbits with kallikrein further purified to remove gamma globulins. The antisera produced contained antikallikrein and also anti-IgG, in spite of only 8% contamination of kallikrein preparation with IgG. The latter antibody was removed by adsorption of antisera with either Fletcher factor-deficient plasma or with purified IgG. Both kallikrein and prekallikrein (in plasma) cross-react with the antibody with no apparent difference between the precipitation arcs developed during immunoelectrophoresis and no significant difference in reactivity when quantified by radial immunodiffusion.
