The interaction of three monoclonal antibodies with human spleen ferritin has been studied. Using titration of various monoclonal antibody-containing media with the immobilized antigen, the specific content of active antibodies capable of binding to ferritin was determined, which was 22-27% for ascitic fluids, 35-50% for total mouse IgG and 88% for(More)
The affinity-purified by chromatography on immobilized antigen rabbit IgG was modified with mixed carboxycarbonic anhydride of DTPA which markedly alters the interaction of charged residues in the protein molecule. To study the correlation between the antigen binding activity and the conformational mobility of IgG, the reactivity of modified IgG towards(More)
Three monoclonal antibodies to human spleen ferritin were produced and their interaction with soluble and immobilized ferritins studied. An immunoassay was developed to monitor the interaction of soluble biotinylated ferritin and the antibody with subsequent separation of the soluble complexes on streptavidin-cellulose. Analysis of immunoreactivities of a(More)
To localize essential epitopes of rabbit IgG, a series of proteolytic IgG fragments obtained by papain (Fab, Fc) or pepsin (pFc', F(ab')2) proteolysis have been prepared and their interaction with sheep antibodies against rabbit IgG has been studied. The data obtained suggest that essential immunoreactive epitopes of rabbit IgG are located in the CH2 domain(More)
The immunosorbent obtained through a covalent immobilization of antibodies on a polyacrolein latex was studied in comparison with the sorbents based on microcrystalline cellulose and with the surface of polystyrene test tubes in a two-center radioimmunoassay for ferritin. It was shown that the polyacrolein latex provides a covalent binding of up to 75 mg(More)
