Abstract
An objective of the present disclosure is to provide an adsorption material that has a carrier material with retained physical strength, and efficiently adsorbs an immunosuppressive protein. The present disclosure provides an adsorption material for immunosuppressive protein. The adsorption material includes a water-insoluble carrier to which at least one nitrogen-containing compound selected from a polyamine represented by a predetermined formula and aliphatic amines represented by predetermined formulae is bound. A total content of amino groups on the water-insoluble carrier is more than 0 μmol and 2500 μmol or less per 1 g, and a content of primary amino groups on the water-insoluble carrier is 450 μmol or less per 1 g.
