title: [Study of human secretory immunoglobulin A. I. Obtaining monospecific antiserum to human secretory immunoglobulin A].
abstract: A method of obtaining monospecific antiserum to the human secretory IgA is described. Immunochemically pure secretory IgA (isolated from human colostrum by fractionation with ammonium sulfate and gel-filtration on Sephadex G-200) was used for immunization of rabbits or sheep. Heterologous antibodies were removed by adsorption with commercial gamma globulin, normal serum, the serum of a patient suffering from A-myeloma with the IgA polymere and purified lactoferrin. Monospecific antiserum to the secretory IgA gave a reaction of complete immunological identity with the secretory IgA and a free secretory component.
