FIELD: medicine, immunology. SUBSTANCE: method involves inclusion of ferromagnetic material particles in hydrogel granule structure. Column with granules is placed to device making an axis and transverse magnetic field gradient. Method ensures to improve rheological property of hydrogel immunosorbents, decrease their compressibility and high hydrodynamic resistance, decrease granule leakage above extracorporal contour, decrease thromb formation risk in column with sorbent. Method is used for extraction of specific antibodies from blood and other biological fluids and can be used in rheumatology and biotechnology. EFFECT: enhanced effectiveness of immunosorption, improved rheological and hemodynamic property. 1 dwg
