Method of immobilizing an enzyme in a bundle of cellulosic fibres for a fibre-bundle dialyzer for purifying blood.

摘要

The object of the method is to immobilize a desired enzyme on the lumen surfaces of the dialyzer fibres typically having an inner diameter of 200-300 microns and wall thickness of 10-20 microns, without prejudice to the chemicophysical, dialyzing and bio-compatibility properties of the fibres.
<??>The enzyme is anchored directly or indirectly through covalent bonds upon activation of the lumen surfaces by circulation through the lumens of an aqueous solution of sodium periodate at a concentration of 0.7 - 21 mg/ml, at a circulation rate of 300-500 mm<3>/minute referred to 1 mm<2> of cross-sectional area of the lumen, at 15-30 DEG C for a time not exceeding 70 minutes.
