Abstract
A method for producing a protein adsorbent comprising a substrate and a molecular chain fixed on the surface of the substrate is disclosed. The method comprises, in this order: a dry-heat treatment step of heating a pretreatment adsorbent comprising the substrate and the molecular chain fixed on the surface of the substrate, in which the molecular chain contains a weak electrolytic ion-exchange group; and a wet-heat treatment step of heating the pretreatment adsorbent in a moistened state with a liquid or steam to obtain the protein adsorbent.

A method for producing a protein adsorbent comprising a substrate and a molecular chain fixed to a surface of the substrate, the method comprising, in this order:
- a dry-heat treatment step of heating a pretreatment adsorbent comprising the substrate and the molecular chain fixed on the surface of the substrate, the molecular chain containing a weak electrolytic ion-exchange group;
- and
- a wet-heat treatment step of heating the pretreatment adsorbent in a moistened state with a liquid or steam to obtain the protein adsorbent.
A protein adsorbent comprising a substrate and a molecular chain fixed to a surface of the substrate, the molecular chain containing a weak electrolytic ion-exchange group, wherein
- when test treatment in which the protein adsorbent moistened with a 20 mM tris-hydrochloric acid buffer solution containing 1 mol/L sodium chloride is heated at 50° C. for 8 hours is performed, a change ratio of a dynamic adsorption capacity of the protein adsorbent before and after the test treatment is within ±5%.
